A couple questions about wiring

[75-K5]

Well I finally got my '68 running under its own power again (sort of). The clutch was messed up and I got that fixed, so the next step was to time the engine. I got it to where I thought it was running well, so I decided to drive it down the road a little. I made it about 500 yards before it started to run like total crap and then it died. I went to start it and nothing happened. It didn't even turn over. I got out and jiggled the starter wires a little, got in, and it started. I managed to limp home, but it died in the driveway again. I messed with the ignition switch a little bit and got it to crank again. When I got out of the truck and touched the door it shocked the sam hell out of me! I crawled underneath and noticed the main wire going from the battery to starter was fused to the header! I pulled it free and tied it to the motor mount with bailing wire. After a couple more attempts at starting it, it eventually quit cranking altogether and continuing to shock me both when I touch the ignition switch and when I get out of the truck and touch it.

Here's what it boils down to: Ignition does not work and shocks me when I touch it.

I have a feeling the entire truck needs re-wiring. I wish I had a picture of the current wiring to show you guys. The turn signals are backwards when the headlights are on, etc. The wires on the fenderwell are a huge clusterf*** of splicing, stripping, and electrical tape. I'd like to re-wire the entire thing. Is it a fairly accomplishable task, or should I fork some money over to a shop? There is an excellent auto electric shop in town that I've taken several other vehicles to and they've always done outstanding work. The only problem is they charge $50/hr labor. I know wiring kits cost quite a bit, so I'd probably be looking at $500+.

I think there was a question in there after all that rambling
