UPDATE: After contacting the seller, they took responsibility and sent a replacement wiring harness. I tested the replacement and it works correctly. Their customer service was responsive and professional, and for that alone they deserve five stars. Bought this in August for an engine swap. From the start, the vehicle didnโt work correctly. I initially believed the issue was engine-related, but after months of troubleshooting, it turned out the real problem was the wiring harness. The harness had incorrectly configured wires from the factory, which made the issue difficult to diagnose.

Ordered as a replacement for a 1999 lm7 5.3 auto rwd truck. It could be made to work, but... Anyway, for the hundred bucks I am keeping it for parts or a stand alone swap later. Its set up for an F body car with the ECU in the cabin, Truck ECU is under hood with the boiling hot engine, its just how GM does things, anyway. Looks to be reasonably well made but read the fine print, it will require changes to things you might not want to deal with.
