Senario: '05 5.3, 4L65, 1 meg PCM installed in a '03 Jeep Wrangler. Only the engine harness was salvagable from the donor truck (totaled) and we were not able to retrieve the accelerator pedal / TAC module.
I have not located a new accelerator pedal because I am not sure which one I need. I am also not sure if I need a TAC module or not? I have all of the pinouts for the engine harness but I do not understand where the signal from the pedal to the ECM to the throttle body is coming from? High speed serial data?
I have seen a few pictures of a 1 meg ECM (aftermarket harness) with ETC and don't see a TAC module being used?
The though has crossed my mind to convert over to a cable TB using an '05 GTO OS but I am not sure if the ECM has the incorporated IAC driver(s)?
Sooo, getting to the point. If you have a truck harness, 1 meg pcm, and no accelerator pedal. What pedal do I need and how do I wire it up??
Thanks in advance!
