Oh crap you are right. I did at first, thought I was done plugged it in. Didn’t work. Fixed issue so they work. I then got that check engine light which makes sense now.You did unplug the battery when you were yanking plugs out of the BCM right?
Those are all lost communication errors.
Glad the negative pull sorted it out
Spares! Dayum - great luck! That's the part number that the Amp guy gave me. I'm mounting the xtreme set - the same drop, but with 4 motors - no idler gear. I found them available on REALtruck.This is the part number. You can see how the part number was corrected for this truck. Somehow I got a mixed up set of parts. It was wierd because the outside box looked like it never had been opened, but the inside electronics box had. I think someone in the warehouse was playing fuck around.
