wiring harness options....

[no1udknow]

So I took the 68 out for a little road test yesterday to assess some carb adjustment/timing issues, and after driving around the block, I pulled in to the drive and popped the hood. I noticed first that I was leaking oil from the drivers side valve cover on to the headers... no biggie, then I noticed smoke lightly rising from the wiring harness running along the groove in the firewall. I quickly shut the truck off and had grabbed the harness, and sure enough, it was pretty hot. It appears to be the original harness with a few cut and pastes here and there. I'm thinking I either want to buy a new harness that has been beefed up a bit, or build my own. I am wondering who has good replacement harnesses. I am not one to toot my own horn, but I am a bit of an electrical guru, I spent many years building, testing, and repairing slot machines and I build custom bikes and their wire harnesses from scratch, so I am not scared to build a harness.... just lazy
