Wire Diagram for 01' 5.3 Vortec engine swap

[Butcherboy]

Hello, Just asking if anyone Has ever built/reworked there own engine wire harness for the LS 5.3 vortec? Id like to try this myself, I have the stock harness and ECM. I will be using a After market chassis harness. The engine is in my 89' S-10 blazer. Current performance might be the one to do this for me, but I would rather save the money and do this at home.

I will still need the ECM burned and programed. If anyone has a over view diagram that shows the color of the needed wires for the engine functions and controls. I can take from there! I have done some marine wiring in the past, and feel I can tackle this!

Any help with this would be great!

Thank you guys!
