Heritage Z

I finally pulled the trigger and picked up an engine for my 92 Z. It's an L76 out of an 08 GMC pick up with 4k on the clock. The guy I picked it up from already had a complete intake set up off of an LS3 except for the throttle body. I am deleting the VVT and DOD. I didn't get the harness with it but I have the ECM.

My question is, what harnesses will work with this engine other than the one from the pick up. Will one from an 05-06 GTO work? Any others?

Thanks.

G8 gt had the l76 as well. I would think anything with an E38?? PCM would work.

Is it going to make a difference if I put a 6 speed behind it?
