To my knowledge there are no dodge autos that used the 29 spline output definitely not in that era. you will need a 23 spline input. they are a different case than the 29 spline and the two inputs don't cross. 23 splines came in any dodge auto through the 205 years.

for the wiring, i dont thing you need the PCM to communicate with anything other than the inputs from the engine and transmission. from there it will make the call for shifting/lockup and acts as the OEM dodge alternators voltage regulator as well as the timer for the toasters. i dont think you need to do anything to integrate it with the GM harness other than give it a good power source and ground it appropriately. the gm dash can be made to work with the correct senders and the stock gauge harness modified for the new engine.
