Over the winter I have been saving up and just started on the new build. My 99 has 5.3 with ls6 h/c/i. It made okay power with a master power turbo, I purchased a s475 and pulled the t56. I plan on wiring a harness to the pcm for a 4l80 by myself so I purchased the internal and external connectors for a 4l80. I found the pins to wire each harness wire to, although some have several spots. If someone could help out that has done this swap by letting me know which pins they used on a 411 pcm that would be great. From what I have read as long as I use the stock 4l80 spacer and TC it would bolt up with minor modifications. Also while its down if anyone has any other suggestions as to things I can do to make more power easier (custom grind cam, etc.) all would be much appreciated.
