2008 5.3 ls-4 wire harness.

[possum1]

The 68 was t-boned and bent the frame severely. We are going to set the new 68 body on a 2008 Tahoe frame. I am going to fit the 08 steering column into the 68 cab. I need to have the wiring harness modified, just to get rid of unneeded circuits, mainly inside the cab. Is there a guide out there that will guide me, or someone that would modify it for me leaving the things behind that I would like to keep.
