72 Dart Swinger 3.6L Pentastar +T5

What a brilliant idea to swap that motor into a Dart!
I'm planning to swap one of those motors as well, but just to an older Jeep, not a A body. Did you find out if the speed input was necessary for the PCM to work properly?

In my few trips around the block, no mph didn't seem to make any difference. I still intend to install something so the cruise control works properly.
