I'm trying to make sense of the duct tape... why?
But on the note of the wiring, reminds me a bit of my 280Zs wiring. There were speakers, but no radio. There was a switch with a cover that I just assumed to be a fuel pump switch, and I accidentally disconnected it. Turns out that switch did NOTHING! It was there for show. I'm sure theres more I'm forgetting, but when I think back on these things I don't regret taking my car completely apart, rendering it immobile quite so much.
