Engine swap is getting closer to a test drive. Still have issues though. NO output from the alternator! ..I think the problem is because the BCM was not part of the swap. So, does any one have a solution. In reading through GM Docs it appears the BCM talks to the ECM via the GMLAN this communication is integral and sets in motion how the ECM will control to the alternator.

Anybody have any suggestions?
