Picked up an OBS 2000 Tahoe Z71 GMT400 platform and want to do an LQ4 swap. I know I can repin the factory harness and add wires for the injectors and coils. Anyone have a link or diagrams? I assume EFI Live will be the only way to program the salvage yard LQ4 ECM with my truck's current VIN in order to pass inspection?

 

I am not responsible for them, but I have seen schematics here---> Wiring Harness Information

 

This is what I used to rework my harness.
