I've been doing alot of thinking about the motor swap i wanna do in my z. lately i've been really fascinated with the ls1 swap, which seems pretty easy(minus the wiring and suspension upgrades). The main thing that has been on my mind about the swap is the engine wiring harness. I'vee been looking for a way around cutting/ splicing/ and crimping. Which leads me to a couple of questions i wanted to ask the z forum gods. Is there a engine harness for z cars that is premade for the 280/ls1 swap or would i have to do the custom wiring?
