- As many of you know, my 1985 F250 has been an ether baby ever since I purchased the truck, it's been getting glow plugs in a can multiple times a day for the last 4 years, when I started uploading short videos most mornings I would start the day with a cold start on the old truck with ether, well well, a lot of fellas seem to be convinced that once you start using ether your diesel engine is now "addicted" to it and will never start without it, I've had enough people commenting that so I figure what better way to prove them wrong than to retrofit a 7.3 idi glow plug controller into the old 6.9 idi, proving that even though ether was used with this engine, the engine is not addicted to the substance.
The 7.3 glow plug controller is a much more reliable system than that of the 6.9, fails less, and won't burn out your plugs when it stops working.
In this video I go in depth and build a custom harness for the glow plugs, change the plugs themselves, as well as instal the glow plug controller.

How dare you deprive that ol sweet heart of Cosby sauce!
I know I know, but now there is more ether for you to use on slave lake haha, we need another video with that old sweet heart! Been watching your videos since I was in middle school, I appreciate your comment!
Totally not surprised to see peg here!
This just made my day!! When are you two getting together?!
@@zwood1100 maybe someday, although he’s on the complete other side of the country haha 😂
@@highostablegarage I’m pretty far south of both of you. Just discovered your channel 2 weeks ago! Love the content. I have a 84 F250 with the 6.9. Broke 2 plugs replacing them, 1 on each side obviously!!
Thank you a customer brought his truck to my shop with your video and I performed this service. Thanks 🙏
Glad it could help!
One thing to note about using the old glow plug harness with the 7.3 controller. The solid state controller measures resistance from heat in the glow plugs to determine whether they get power or not. The old harnesses even on the 7.3’s have many splices that are usually corroded and in bad shape. This will make the controller think the glow plugs are hot when in reality it is just seeing the resistance of the bad harness and won’t give the glow plugs power. I recommend either installing a new harness (which aren’t cheap) or making a new harness completely replacing the old garbage that will most likely cause hard start headaches. Great conversion! Have a good day!
I wired a hot wire from a momentary switch to the trigger post piggybacked over the controller trigger wire to jump the GP relay on the 6.9 I had, that’s how all the 6.5 GMC’s at work were set up and it worked great as long as you knew what you were doing (as in don’t hold the button so long the tips on the glow-plugs swell up like a balloon). I just used mine to give it a little “extra burn” time on the new ZD-9’s I put in it. One nice thing was doing it that way allowed the original controller to still function when I wasn’t overriding it. the “wait to start” light would even come on when I hit the button (as you’d expect, idk why I thought that was so cool).
What a great 👍 video. I live in a snowing area in USA and this conversion is just awesome 👌. Thank you for sharing.
Glad you like it! Yeah I would say it’s one of the best upgrades you can do to an Idi
Love the video the seven threes is probably one of the most reliable motors I know👍
They are damn tough haha
I love my 7.3, but I hate the cavitation...
Great video Bud! I'll be doing that mod!!!
Just found your channel. Fellow New Brunswicker here! Bought a '01 F-250 Super duty with 7.3 powerstroke in November. Love diesel engines! Love your videos!
I’m glad you like them! Glad to find more NB’ers on here
Working in an old dairy barn! I like it. I wonder how hard this job is gonna be for me working around the old banks sidewinder setup on my 86
Was looking for a video fixing the hazard switch (some owner previously removed switches and did some weird rewiring, absolute cable mess) but ended up watching this video and now thinking to go for this glow plug controller for my F350 6.9 IDI. Great video on the topic!
Glad you liked it, this is definitely the best way to have an Idi setup for cold starts
With a few hours of your time what a difference. Great video. Love the content . Cheers
It’s night and day haha, its wild how good the 7.3 system is to the 6.9 original
Thanks. Also is the stock gp relay required to make this work or can it be removed?
@@codywoodworth5480 I used the stock GP really for the 6.9 basically as a junction box in the video but you could completely delete the mechanical 6.9 controller and gp relay if you wanted
Always loved the sound of those trucks firing up! I know they're under powered compared to today's diesels but they're sure easy and cheap to work on by the same comparison. At the end of they day, I love my 6.9.
Thanks for the information. I'm going to attempt to simply replace my glow plug controller. I've heard horror stories of replacements failing after 6 months but mine has been in since at least 1994, when my IDI came into the family. It may be factory original from '85 and it's just now failing. Maybe they don't make the replacements as good as the originals? If that doesn't work long term I'll go to the retrofit.
Good video!
Glad you liked it
It’s 7:52am I’ve been watching your channel for like an hour- so many shorts and couple videos. I’m only a couple minutes into this 3rd video now, can’t tell what order I’m watching anything in and I still have yet seen you NOT being in the snow. It’s like perpetual snow.😂 I mean, I’m enjoying the content (keep up the great work💪🏻) I’m just wondering if you’ve ever seen the bare ground or do you just live at the North Pole.
Haha 😂 for a few months out of the year the snow usually stays, likely end of march it will clear…hopefully haha 😂
Peg sayz Hi! LOL great video!
Yes sir I saw haha, glad he enjoyed item, glad you enjoyed it.
U think u can make a video on how to set up a push button for the 6.9 setup? And maybe a once over of how all the plus are wired up mines very confusing
Nice
yes sir
Got a video explaining how to install electric fuel pump?
What wires should I change on the GP controller to have a manual momentary switch?
good show just have question. will that location give the controller enough engine heat to work correct
Oh yes, it’s actually closer to the exhaust manifold than the factory location so if anything it will cycle the plugs off quicker than the intake location,and is a very similar location to what the turbo idis used.
I have a 1983 F250 4x4, 6.9.
Don't mean to ask a stupid question, but. . .
Could I put the new improved 7.3 controller where the original one was and toss the old one?
Awsome vid by the way.
Watching from Kelowna, British Columbia.
The controller relies on engine heat to know if it should kick the plugs on, so he was trying to get it as close to where the 7.3 has it which is behind the air intake in the middle of the engine. Dont know if it would get enough heat to register properly mounted where original was. I thought about doing the same thing.
I just swapped the 6.9 glow plug relay for the 7.3 today, and i have some questions. What is the filament for exactly? And im not sure if the relay is supposed to get 12v constantly on the coil, but mine does currently and im afraid of buring up the glow plugs again.
👌
I never had a problem with 6.9 glowplugs. The 7.3 everyone I know had problems with that system
Every 6.9 I’ve seen or heard of has had the mechanic controller seized on it, maybe if the trucks were well kept all its life it would be a different story.
@@highostablegarage not sure. Mine never had a problem. I did have 3 glowplugs out at once but it started just fine and all I had to do is replace them. My buddy with a 7.3 had to wire a manual switch to his because he couldn't get it to work right. Maybe it's just my experience.
@@nohtgonahappen7314 hard to say, I might have just had bad luck with the 6.9s and you might have just had bad luck with the 7.3s
@@highostablegarage could be. I'm a firm believer that ever engine to an extent Is it's own beast .
@@highostablegarage might just be that nice maritime road salt ruining everything like it always does compared to the American south...
just out of curiosity, is it possible to run the new 7.3 controller to the factory 6.9's spot, or does the engine heat matter too much for that? I'm gonna be attempting this conversion on thursday and im not sure how confidently i can try to make my own bracket lol
Wondering the same, how did it work out?
Parts numbers would have been good. Im doing the same upgrade.
Just put some in the description
Awesome man! Thanks!
So can I change my glow plugs to the zd9 plugs and leave the 6.9 style solenoid and just put a push button on the solenoid trigger wire
Sure can
Nice upload! Why cant you use just a heavy duty relay like a Stinger made for those crazy amp set ups? My new low mile 87 6.9 has previously been changed out to a 7.3 GP contoller but still not working I just came in to eat supper before going back out on this baby Nie video I enjoyed it!
You most likely could use one as long as it can handle the current, but the 7.3 GP controller where it shines is the little solid state computer on it, makes it so as long as the computer is working and your engine is healthy, the glow plugs shouldn't ever get overloaded and burnt. I appreciate it, glad it might of helped!
Does the controller need to be mounted far back like that?
Technically no but the metallic strip needs to accurately match engine temp for good starts
Use 5.7 olds diesel 12v glow plugs will work
Any video plans for the trip?
The Kms per day is the round trip number I have drive everyday to go to school, that is for the next 45 days if that’s what you are referring to. If you are referring to the summer trip, yes that one will be documented for the 2000kms or so
@@highostablegarage that sound like when my grandparents talked about having to walk across the lake mid winter in -30 to school 😳
Didn't know about the summer trip but looking forward to it 👍🏻
Yeah it’s a long commute round trip haha 😂 And yeah, should be taking some old rigs on a road trip this summer
Could you run the 6.9 plugs with the 7.3 gpg?
Can’t see why not, I quite like the bullet style connector from the 7.3 system, the spade 6.9s tend to break off
How do you know if your controller is stuck
Wouldn’t activate glow plugs, mine is seized internally
@@highostablegarage do j just pull one reconnect it to the harness and see if it glows
So… when the glow plug pressure switch seizes solid, it becomes a solid state control?
I fail to see the purpose of this video then.
Just kidding. Or is it chiding. I nearly failed English class.
I'M LOOKING FOR ONE LIKIT. LAT MENOU IF IS FORSAL
