Works on... when you get down to it. Throttle position, and Idle control shouldn't have a year limit. you have this no matter what year it is.more than likely with the same number fo wires, etc. what this video shows is how to do this on 99-2002, the concept and workings should still be the same.
This only works if you have the right ecm. Most ecm’s are not set up to run the stepper motor that controls idle control valve so not everyone can just add some pins to their ecm and have the cable throttle body work. You must of had one of I think 3 dbw ecms that will control a iac valve.
@rrwebster where'd you get your info on what pins to change and stuff? Also have you tried starting it yet??? Just curious because I'm trying to convert DBW to DBC in a similar engine myself
One new thing that I learned is that you have to remove all of the drive-by-wire crap. You cannot leave it on there. They won't run right? I got my info by trial-and-error took apart the wiring harness put it on another one. The pinouts are available on the internet anywhere. And yes, it does work.
@@rrwebster okay cool thanks a bunch! Is there any way you send me the link to one of the websites you looked at? I can't find any anywhere I've spent hours searching
@@AirsoftCarter3 I had another one of these come through my shop and had to dust off the video.... I have another mistake/miss spoke in there.. I say the first two wires are green and black,, not true for the IAC it goes 76 is Light Green and White, 77 is light green and black, 78 lt blue and black and 79 is lt blue and white.
@@rrwebster what dbw stuff do you have to remove? Pedal obviously, but once your old wires are on your iac and tps and repinned thats everything isnt it?
All he’s doing here really is swapping how the throttle body communicates with the ecm from the gas pedal. Instead of the wire system tells the ecu to give more power the cable says this is my position on the throttle body and the sensor tells the ecu to give more or less. Installation is recording what you removed from the other ecu harness to the new harness your changing. Gotta pay attention.
@@jameerchavis6135 your ECM should work just fine there's one setting in a table that's got a digit in it if you have drive-by-wire it really doesn't do anything the fact that you have all the wires in the correct spots after you've done this makes everything work right
I did a LS swap I have a 05 but I put a 02 motor in it. I’m getting reduced power and it’s saying I lost communication with throttle actuator control module and pedal position sensor but it runs right for a little while then I have no power is it because I used the throttle body from my 05 on top of a 2002 motor? Or are they compatible? Because I think the 02 was drive by cable but the throttle body I’m using from my 05 is dbw
Having the the two different years if they are both drive by cable and or drive by wire wouldn't matter the problem you are running into I'm sure is that you had drive by wire and now you're you're using drive by cable and you don't have the wiring correct and you need to to follow what this video shows you if you were drive by wire but you got to know that before you do any changes you got to know whether you were driving by wire or drive by cable
Actually if I think what I would have done if I were you you say you have an 05 and you put an 02 motor in it well that's all well and good you could have or should have used the hardware from the 02 but used all of your harness and when fuel rail and all of that stuff from the 05 and then you would have no problems at all
I have a truck that the vats are messing up. And I have a ecm that is drive by wire not cable, but the ecm I have I already have vats turned off. So my question is Can I just put my drive by wire Ecm into my truck with a cable. And will it work and not brick it
If your ECM that has no issues with vats or anything works I'd use it. Remember there is no code related to drive by wire vs. Drive by cable if all you're doing is changing from one to the other. Let me re-emphasize that yes there is a a 1 or a 0 in a chart was in the software component of the ECM however that is not what controls your engine it's just a code in a table
The only code in that computer that has to do with drive by wire vs. Drive by cable and there is a 1 digit entry in a I'm going to stay charged but it's Micah it's like a chart that is the only thing that has anything to do with drive by wire or drive by cable that I do not believe matter and I say that because I have messed with it I've changed it I have made it one made it to be done many things it makes no difference it's whether or not you have the wiring in place I flash every ECU anyhow because I do it for the security and the key to know how the key can stop the if you don't have the right key that's a flash them all anyhow so I got can't say that you don't have to but I don't believe there's any reason to
miss spoke in there.. I say the first two wires are green and black,, not true for the IAC it goes 76 is Light Green and White, 77 is light green and black, 78 lt blue and black and 79 is lt blue and white.
Well that's not how it works the wiring from the throttle the actual throttle pedal goes to another box that is a controller and then that other end of that cable from the controller there's two plugs in the controller one goes to the throttle pedal one goes to the computer. So there's no correlation at all between the throttle pedal and what's going on
I got a 6.0 out of a 2001 Yukon Denali that is dbw and I want to convert it to dbc all going into a 1983 c10 and ordering a harness for dbc what would I need to do to make it dbc just switch out the tb and what else
Not knowing how the harness is wired...will it have tps and idle controller.... Yeah you should only have to swap the TB out. If everything else is covered.
well it has 246k on the dash and I replaced the transmission but I got it installed and it looks like coolants leaking out the back of the engine some were so I was thinking of cutting my losses and just getting a 5.3 setup out of a 2000 Silverado or something similar. but it's a 95 Yukon gt and I'm just not sure what I should do yet
This is 2003 and earlier the computer should have a red and a blue port and that's what plugs into the computer if you don't have a red and a blue then you've got a newer computer and a newer wiring harness and they aren't going to match this was not done for the newer ones I am however very very close to doing a two thousand six which is the green and blue computer and that one I'm going to do probably right from scratch because it's a drive-by-wire setup and I'm using going to be using drive-by cable
First I'd like to appologize for not answering sooner... I am supposed to receive an email for every comment, this is the first I've seen this question. The blue/green pin out is the same almost... 47 is not used in the blue/green config this is for the map sensor.
If I was to get a stand alone harness and will have a th400 ecu with drive by cable ecu and drive by cable throttle body will I still need to technically mess with the wiring if I do all of that? NEED HELP ASAP
I'm reasonably certain that a standalone harness is already drive by cable a turbo 400 doesn't need any programming at all. So yes you're right you don't need to do anything at all if you purchase a standalone harness.
This video was a tremendous help to me. Thank you very much!
Glad it helped!

What if I bought pigtails, all wires same color, what would be a diagram for wire positions
just wanted to see you actually install the throttle body and cable

So would I have to get a DBC pcm or would I still be able to use my DBW pcm that’s all ready tuned??

So the way the harness was connected to the computer on the dbc has the be in the same pins in the dbw computer right
If I have a dbw engine can I just get the harness reworked to dbc or would I have to get a dbc harness if I’m doing the conversion?
either or... reworked or DBC harness is no real difference in the end, lots of work involved in reworking a DBW to a DBC.
So did you use the same harness ?
I guess same harness,, Yes
To be totally honest, I don't remember. There is no reason that you can't.
Would it be a similar process with a 5.7 hemi
Yes it could be, you're talkin two different manufacturers,

No

Yes it's possible... Components for the most part are the same 1999 through 2006
If there is something more specific you are asking let me know.
What do you mean by red or blue
There are two connectors for the computer, one is Red and one is blue.
The wires dont match to the ones I'm taking off

Did it ever work
