TDI_Manche Posted November 4, 2021 Posted November 4, 2021 I have vv diesel swapped my 1987 jeep comanche. I chose to keep the AW-4 renix era. I am not struggling with how to build the harness. I have interior swapped the comanche too so all electronics are running off a 1998 Cherokee ecu. I have the TCM and ECU for the renix era auto. I connected the kickdown cable and the TPS sensor to my vw pedal. Can I run the TPS straight to the TCM along with 12V and ignition, or do I need to run it through the ECU for the correct voltage? Do I only need the TPS and the kickdown cable as an input to run the trans?
ghetdjc320 Posted November 4, 2021 Posted November 4, 2021 The tps voltage input is 5v. You can get a nice little 12v to 5v step down transformer online. You should be able to nix the renix ecu and just use the tcu stand alone. A super nice albeit expensive option is a compushift tcu. Gives you full control over all shift points which may be very helpful in adjusting those shift points for a Diesel engine
TDI_Manche Posted November 5, 2021 Author Posted November 5, 2021 I was looking at getting one of the 12 v to 5 v step down. The TCM pin 1 is supposed to be a 5 v supply but I can't get any power out of it? Ill try to find what is missing but if not found ill get the stepdown!

Yeah the step downs are only a few bucks on Amazon for a fully potted waterproof version. Actually just ordered a couple more for my stand alone project
TDI_Manche Posted November 9, 2021 Author Posted November 9, 2021 I tested my 12 to 5 volt converter and it didn't show signal changing between the solenoids. Any Idea what I might be missing? One thing I can't find is the pinout for the grey aw4 connector. There are 4 dead end wires I don't know what to do with. but this is how I ran my wires. Might be missing a ground. For renix era, are all fully black wires grounds? there are unlabeled wires from the tcm that are black which I may attach to ground.
