The Ram harness is different - the PDC on the one I looked at was in a different spot. The PCM connectors are the same. I ran a 94-95 Mopar 5.9 computer in my truck. The only issue it gave me was it tripped a code for tranny temp too low. My truck does not have a tranny temp sensor to begin with, so I assume that was specific to the 5.9 powered Rams.
If you are desperate I am parting out my 92. Have the engine harness already pulled. Also have the MP PCM.
