The 87 Charger I got from my brother has a stage 2 already in it.I am not sure he has the wiring right or not.He used the kit from forward motion and has the number 16 and 20 pins for the ais. I seen the sticky says something about moving #4 blue to #4 red and also #14 blue to #9 red.Do I need to do that? Maybe this is why it won't idle right.I am not sure if he did that and don't know if it is required .If anyone knows please tell me..
