Alright, now that i have conquered most of my issues {or so i think} the last major hurdle presents itself.

Wiring Diagrams. I have been able to find NOTHING so far {except solicitations to pay for illegal downloads, shame on you know who you are!}

Need to know what the PCM wants to see, and how it outputs to the trans.

I REALLY dont want to do an entire dash harness swap. If i can, im just going to snip out the PCM and eliminate all the crap so i have a nice clean stand-a-lone harness/pcm

Thanks for the help!

Not sure if trying to run the TCM alone will work. As far as I know they require communication with the engine PCM.

Have you looked into the MEGASHIFT by B&G? (The MegaSquirt guys)

It is a DIY controller for electronics controlled trannys (Your RFE)

Not read up on it totally so I'm not sure you HAVE to use it in conjunction with a MegaSquirt controller.
Lemme do some checking for the specifics of the TCM info you need and I will PM you if I find any usable info.

Its a stand alone controller, does not need a megasquirt to run.

There is no Engine Computer in this truck, There is only One PCM.

It controls the tranny, grid heater, cruise and i think the abs. Its the same PCM chrysler uses in gas truck to control the engine and transmission but about 2/3rds of the pins are blank in this one.
