Official NBS V6 to GENIII V8 swap Guide

yep... it's only been stated in here a million times that the 99-02 harness is different than the 03-07, and you need to get a harness & computer that matches the year of the truck. for the 03+ guys who want to keep the throttle cable (versus an electronic pedal swap), you'll need the harness from a van.
if yours is a manual trans, you'll also need to ensure there's a jumper wire in the fuse block for the clutch safety switch.
