Your not going to beleive this but, the last 3 pictures are of the harnesses already reduced to only what I need.
Heres what I removed. Just goes to show you how heavy these harnesses were.
I forgot to mention that I'm getting rid of all my old s30 wiring and using all of the 350Z components. Everything important uses relays and has newer version fuses. However, I'm only going to be using the headlights, taillights, brake lights, and turn signal lights.
Speaking of using the BCM I met a guy at the MSA show a few years back that had an entire 350Z platform on his s30... he had like an s200 front end...funny looking thing. Anyway, I remember he did use all the functions of the 350z from wipers to keyless entry. At the time I was thinking why and wow that must have been hard. Now that i'm in this deep I'm realizing that it's as easy as plugging the components onto the harness.
