did a hemi swap in a 2003 ram that used to have the 4.7l engine in it, i changed every harness from the 5.7 hemi truck that i pulled the motor from. only one not changed is the 2 doors and the interior light harnesses, i now have no speedo or gas gauge, everything thing else works and drives and shifts fine, i should mention that the truck i put the engine into is a reg cab short box with 2 wheel abs and the swap came from a 2004 crew cab with 4 wheel abs, any suggestions would be great

 

What did you do for a PCM?
