Default 2002 Monte SS L36 to L67 swap

Blew my n/a motor at 132,xxx so i decided instead of staying n/a i wanted something more. i went and bought a l67, wire harness, and pcm from a rear end wrecked '98 grand prix gtp salvage yard with 110k on it for $500. Got the motor in no problem but now im a little stuck on the wiring harness, for the fuse/ relay box it only came with one 3x12 slot box and i cant find anything on it as far as what fuse goes where. If anyone has any idea i could use the help😅 thanks in advance

Other than a couple wires, the two 3800s should be near identical. Put your original harness back in and use that. Should only need to relocate the map plug (as its at the back of the engine vs the pass side) and run a wire for the bbv solenoid to the pcm. There are 'l67 swap' wiring kits for this for like $20.
