How to use the dome light to wire in approach, courtesy, rocks lights to automatically come on and come on with the use of a switch with having the dome light or cargo lights on.

It’s my opinion all the lights listed below can come from the same light source but how they’re activated is what classifies differently.
Approach lights:
activate when Fob enters the trucks driver or passenger door radius. If your dome light does not turn on when you approach driver or passenger doors the dealer can turn on this feature during your next visit.
Courtesy lights:
activate when trigger by unlocking via remote or opening a door.
Rock lights/under vehicle lights:
activate by switch when desired. - Jak na to + styl
You are spot on, i did the same using a switch leg ground for approach affect, except i did a constant hot fused from battery to my rgb led controller for my pb switch affect as the dome circuit woulda been over loaded, great video and advice keep it up,
Glad to hear! Thanks bro.
I just want to say this video inspired me to do my rock light setup on my Tacoma. But I took it a couple of steps further. I separated the door and wheel rock lights to be on there own circuit. I also installed additional switches inline of the switched ground heading to the relays. I did this to turn off either the wheel or door or both when unlocking the truck or approaching it. So I can have the door and wheel lights come on, or just have the wheel lights come on and the door lights are dark, or just have the door lights come on and the wheel lights be dark. Also installed switches with the constant power so if I wanted to I can have all the lights on with the truck off and locked. Also did the same for LED strip inside my grill. Thanks for the video...
Wayne…maybe you can confirm my comment (one before yours). I think the on /off switch needs to be connected to Blue hot wire vs negative Yellow? Or do separate hot source to the on/off switch?
@@viacarlosa I want to know this also
Aloha, I'm trying to do the same type of setup with my Rock lights. I want them to come on when I unlock my truck with the remote. I've been hoping to see someone that has done this type of setup. Gonna purchase the Relay from Amazon and see what happens.
Thanks for the great video.

Also I have the mictuning rock lights and the are a 3 wire system. How would I wire those up, do you know. You input is greatly appreciated.
Thanks bro. It’s really straight forward as for the 3 wire I’m not I sure but it would be much easier to use a wire led. And Mictuning also sells 2 wire lights.
Wonder if there is a way to increase to approach distance to make the lights come on sooner
Hi there, love your video but i’m having a hard time applying it to my setup, you mention in other comments helping friends wire this to a switchpro, how does that differ from what you have here?
This is so cool. I want to do this.
Question- do the courtesy lights come on if everything is off and you turn on your dash light manually? I often find myself at night needing to Dig through my glove box and turning the light above the headunit on to see. Will turning this on send power to those footwell lights? Or is this wiring the light in the back seat area of the roof (in which case I don’t care)… I did this in my Jeep awhile back and had to put a diode in cricut to prevent this but not sure if it would work here. Thank you so much for this video though- very helpful
I want to say I connected everything like you said and I get nothing when the door is open but when I click the switch the lights come on and off. The power comes from the 12v. Do I need a capacitor?
AWESOME VIDEO!!! QUESTION on Yellow vs Blue. In diagram for relay, you mentioned blue from A pillar is power and Yellow is ground. But in min 8:53, to you connect the switch, you connect the green wire to the “Yellow” wire for power? Should it not be green to Blue??
Any idea if the factory under-vehicle lights work like this as well.....?
Can you help further with the switch. I have everything hooked up the way you show (I think), but the rock light switch is not working.
I think I finally understand what you did. So your diagram picture and your explanation I understood differently. You connected your hot wire from your switch to the 12v + blue, The negative wire on the switch to 86 on the relay. Then connected 87 and 85 to a ground. 30 on the relay to the negative on the rock lights/footwell lights. Then Where did you connect your rocker lights/footwell lights positive wire? I connected my switch to a 6 panel fuse box and my rocker light positive wire to the 12v blue wire. The lights come on with the switch but not the door.
Did you connect the dome light ground wire to 87a like in the diagram?
I like the concept. I'm not very confident in wiring stuff like this. Good vid though!
Thank you! I’m sure you and a freind could knock it out no problem.
I wanted to ask what kind of lights are you using ? Or where do you get them from?
Aut of all the videos i have see for this project this is the most decent one i see or the best! 😅 i just think im too slow to do this by myself…
Haha thank you. I’ve walked a lot of people thru this.
Can i just pay to do it and get over it 😂
hey buddy, love your video, can we do this to a gen5 rav4. is there any option that we can tap into the fuse box instead to pulling wires from A pillar? i just want the led’s as an approach light.
I’m sure it can be. I don’t have a rav4 tho so I’m unable to help you.
Has anyone attempted installing cab clearance lights?
If I don't use a switch, would I just leave pin 86 empty?
Does this work with a sr5 3rd gen? I have a H key. I may be able to wire it the same way but leave out the wiring that will come on when I get close process.
I also want to us running board lights. I was thinking that I would have to use a relay. Do I need a 4 pin or 5 pin relay. I don't want to use a switch. Just hardwire turn signal, and when door opens.
Are you having any issues with that relay? I've heard it can cause problems due to the dome light running off a PWM circuit. Have you noticed any intermittent on/off issues? I was wondering if it would be better to use a solid state relay?
Nope never. PWM is just how it ramps on and off.
I purchased a lighting kit and it only has a red and black wire. It also has a switch already on the lights so I do not need to install one. My idea is the same and want to have them turn on off when the truck unlocks or locks up again, with the dimming feature of the dome lights. Do I tap into the blue and yellow at the A pillar on the driver side? Or do I tap into the dome left and right wires at the switch panel on the driver side for this function to work with mine? I simply plan on leaving the switch turned on at all times so they function as courtesy lights.
You need to follow the wire diagram exactly it will work and it’s the only way to properly activate the lights via doors locking/unlocking, on approach, and with the a switch. If you do as mentioned above and leave the switch on to use courtesy light you won’t be able to manually turn on the lights on if you wanted rock lights on while off-roading.
Awesome mod and genius use of the factory wiring features! I've done simple wiring stuff but this one is next level, I'm willing to give it a shot though! I actually just installed the auxbeam 8 gang switch in anticipation of having many accesories. Would I be able to use that for the switch portion in your diagram? If you require more info, please let me know.
Thank you! Yes I recently just helped someone do this with their switch pro controller. Just put the auxbeam wire where the on/off switch is located in the diagram and you be able to turn on manually from the auxbeam controller.
@@Tcodyw88 Awesome! I thought
that would be the case but figured I'd still ask. One last thing, the link you provided in the description for the relay has a slightly different diagram than your's in the video. Can you confirm that diagram on Amazon is the same as yours but with 30 and 87 switched places? Thanks again for your! reply
@@Steven-te8yd No worries bro, let me know if you have any issues.
Also yes the diagrams are still the same.
@@Tcodyw88 hi there! So after inconsistent weather I finally got to this and I'm happy to report that my rock lights have achieved the dimming affect. However the only part missing now is I was unable to manually power them on using the auxbeam switch. Eveything is wired exactly like the diagram. Any advice?
I have the meso puddle lights and was wondering couldnt i just tap one of the wires that are in the a pillar for my rock lights?
Yes sir.
@@Tcodyw88 do u know which wire to tap into? U think i need a fuse for it too?
I can't wrap my head around wiring it in this fashion.. i'm not really as used to automotive as house wiring. Is there a reason you can't just make the dome light power trigger the relay to power the lamps with a 4 pin relay thats battery to switch to relay and fused hot to relay for the power that goes out to the lamps from pin 30 ? Meaning the dome light hot as a second trigger for the relay ? I already have the setup wired and working great , it would just mean adding the second wire from dome light to the trigger pin. Does this make sense to you ? I know multiple ways to use relays and this is the way i had chosen.
The dome light has constant power (3rd gen) and is and regulated by the grounding wire which does the dimming. This is why I use the ground wire and not the power wire. But there’s a ton of ways to wire something. This way keeps the dimming, approach, switch features.
i want to try to replicate this, only difference is my rock lights are running to at spod bantomX, so im thinking i would have to use a trigger function in the switch panel, im lost 4sure on this one
I too am looking for this solution. I believe the spod trigger only needs a positive/power source. Great video, might be more than what we need to do. I hope anyways.
Just wondering what relay you used, if I could please know
Yes it’s called a “5 pin SPDT relay”
Can i tie into this circuit for courtesy lights but also run to a power so i can use the rock lights while off road?
If you follow the diagram that’s exactly what will happen.
Did you add a second relay? You said something about it being tucked in the corner
Nope, just the one relay was used like in the diagram.
This would work without the need to add an additional switch, correct?
Yes it can.
So will the rock lights work normally or only as courtesy lights?
Yes when you press the button they will stay on.
I understand how to wire the relay to the switch, but how do you wire the orinal wires from the rock lights to the relay? I have 3 wires from my rock lights, a back, a red, and a blue.
I have no idea what rock lights you are using, but for a standard 2 wire rock light the power(+) wire goes directly to the battery and the negative(-) wire goes to terminal 30 on the relay.
@@Tcodyw88 where would the 3rd wire go that makes the switch light up?
@@staceycousins3581 you can send me pictures of exactly what your talking about on Instagram @tvodyw88. I’m not sure if you’re referring to a 3rd wire on the switch or the leds.
I used a bed light kit just 2 straps and I'm out of blanks to add more switches. I got everything wired up per instructions minus the switch. The switch that came with kit I have to leave on so it dims and stuff. Do you know how I could wire in to cargo switch so I could turn them on or off with it? I tried purple wire as seen on forums but that just made cargo light stay on always and no control of under lights
I’ll look at the cargo light wiring and get back to you.
@@Tcodyw88 thanks. I wired relay same as you but when I turn dome switch to on the under leds don't come on. When I approach when locked or open a door they do. Only difference I used 12v constant instead of blue wire.. Any ideas?
@@DanielH97055 without seeing your actual wiring I’m guessing. But i think you pulled the ground wire from the dome light to the relay. Pull the positive dome light wire to the relay and that should solve your problem. Let me know if it works!
@@Tcodyw88 I attached to yellow wire ground per instructions in a pillar. Blue is continous power and said could pull that from battery
@@DanielH97055 I’m referring to the dome light switch to active the relay. If you’d like message me on Instagram tcodyw88 I’ll explain with a picture.
Ok I followed ur diagram but I connected straight to da battery instead of da dome (blue wire). So I used a switch illumination harness from tacomabeast. So green wire goes to pin86 n da red wire u connected to dome but I tapped into da rock light positive (wire to battery with inline fuse). Everything worked as supposed to but when I use da switch in da cab to turn on da rock lights it also turns on da dome lights. So I untapped from da rock lights positive wire (da inline fuse to battery) and used an add-a-fuse but same result, dome light turns on with switch. Any clue wat I did wrong or missed?
If you’re talking about the ch4x4 switch’s the green wire goes directly to 12v constant power and the red wire goes to 86 and when you push the switch it send power to open the relay. 87a and 30 are connected when 85 and 86 don’t have both a power and ground on each, once 85 and 86 have power and a ground then 87 and 30 become connected. The ground wire from the dome light should only be used to trigger the relay to open (86). The dome light should not be directly wired into the rock lights, that is the purpose of the relay to keep everything working together but not directly wired together.
@@Tcodyw88 ok I double check n I was mistaken I did green wire to an add a fuse n red wire to 86. On ur relay/diagram 85 is positive n 86 is ground?
@@spaGEHdee no in the diagram 85 is ground and 86 is the positive wire that comes from the switch when it’s pressed on.
@@Tcodyw88 I got rock lights + to battery, rock lights - to 30pin, got 87&85pin to chassis(ground), got dome light - (yellow wire) to 87a, in cab switch green wire to an add a fuse engine bay fuse box, red wire from in cab switch to pin86. idk why my dome light comes on when I turn on da switch.
@@spaGEHdee based on what your saying is happening try switching the two wires on 87 and 87A
What lights did you use? Link?
They’re discontinued unfortunately, sorry brotha.
@@Tcodyw88 damn, were the lights you used three wire lights (red, black and white)? or just a normal 2 wire light? (Positive and negative)?
@@eddier9921 they are normal 2 wire style led light. (Positive and negative only)
@@Tcodyw88 okay okay, one more question. So the lights you used don’t have a specific dimming function? All you did was used the relay a certain way to get it to dim?
@@eddier9921 correct the lights are on/off only with no other functions or controller. The Tacoma ground wire indicated in the video already has this dimming feature so make sure to use this exact wire to ground the lights.
Hey there’s two blue cables.
You identified that the larger draw on the circuit would fry the Blue wire. BUT! You didn't take into account that the Yellow is in danger of frying because it will see the same draw as the blue. The way you have it wired you cannot run the rock lights as courtesy lights for extended period of time, you will fry the Yellow wire.
The way you can check this is leave your door open for a few minutes it will power the rock lights and your Yellow wire will start to heat up.
Are you trying to say the yellow ground wire to the relay would fry? That wire is just activating the relay so I don’t see how that would happen. If your having that issue I would double check your wiring. If your just theoretically looking for issues it’s not a problem, I have run my rock lights for HOURS with out issues in this wiring configuration.
Also I saw your previous comment but wasn’t able to answer it fast enough before you deleted it.
@@Tcodyw88 If you're using the yellow wire as your dimmer? Then yes it can fry depending on the load. But if it's only activating the relay? (Which your drawing doesn't show? Looks like the push button switch is activating the relay) then that wouldn't be an issue. Your rock lights (When using the push button ) are on a separate circuit so yes you can run the rock light for hours with no issues. But when your rock lights are on the dimmer/Dome circuit? It can melt the yellow wire.(Depending on the amount of rock lights you have.). This is just going off the drawing you have in your video.
@@toku58 Again I’ve run this set up for almost two years without issues. I’ve personally done it to multiple 3rd gen tacomas as well as walked people thru the process used in this video, none have had issues. If your looking for help ask a direct question and I will help the best I can.
@@Tcodyw88 How many of those lights can I run safely on the dimmer yellow ground wire? If the blue wire can't handle the load on the wire? How can the yellow wire handle the same load? You stated that I would need to wire the power direct for a larger load (Amazon lights) What is a safe number of Amazon rock lights to add to those wires?
What?
