Question about wiring and paint/body work

[Ryan99]

I'm probably a ways off from either of these, but I'm trying to get an idea how to plan this project out. Right now I'm in the middle of redoing the suspension on my truck.

In order to get it driving (and inspected) it's going to need a considerable amount of rewiring. I could try to make the old wiring work, but it seems like a wasted effort. The old wiring is a rat's nest of a disaster. I'd like to buy a wiring kit and rewire the whole truck.

Eventually, I'd also like to have the cab blasted before I start any real body work. Would it be a waste of effort to rewire the whole truck, before later tearing down the cab to get it ready for blasting?

If I were to rewire it after blasting, is this something normally done after painting or would it need to be done and taken back apart anyway when I'm going to shoot paint.

Just trying to get an idea of how to proceed. I'd love to get this thing driving before I start body work, but I'm not sure if rewiring and then taking it all back out is a stupid plan.

I'm new to this so go easy on me.
