As I'm getting closer to finishing the 5.3 LS Swap in my 06 H3, I'm finding all kinds of little electrical connector issues. Some connectors from the the donor motor don't match some just aren't even there compared to the wiring harness. I bought an OEM wiring harness for an 08 ALPHA and a 5.3 out of a Tahoe. As far as the some of the connectors not matching I can deal with either replacing the sensor or changing the connectors to work. The big one is the blue connector on the ECM. The 06 L5 computer had a slightly smaller connector and had the lockdown posts in a different position. Has anyone dealt with this problem and if so how did you fix it. The computer I bought for an 08 ALPHA works with the new wiring harness but will not connect to the blue connector on the truck that I believe runs power to the body control module ( not 100% about this). The company I bought the computer from said its not possible to do this swap.
