Does anyone know about this harness (p/n 12480055)?? I found it in the GM Performance catalog. I was hoping that it was the same or similar to the Painless harness. I am installing an 2000 Camaro LS1 and the 4L60e trans into my 1970 RS Camaro. I have already installed the (12480033) LS6 Hot Cam kit. Any info on this harness, ECM, and programming will be greatly appreciated.
