When I built my '56 Chevy straight axle gasser with the 348/434 engine, I stripped out all the wiring. I looked at several different manufacturers and one day, I went to a car show sponsored by Good Guys. I bought a wire kit made by EZ Wiring. It had 18 or 22 circuits , way more then I would ever need. Even came with a new fuse box. It didn't have the whistles and bells that other kits had, but it wasn't $500.00 either. I looked it over well and bought it for $180.00. I studied the directions for a few days and then followed them. I kept the harness together and laid it on the floor of my wagon. A lot of wire. It can be overwhelming for you if you allow it. I believe the harness was divided into 4 quadrants; engine, dash/interior, front end and rear end. I did one section at a time and checked everything before moving on to the next section. When done, I certainly had a lot of wire left over and everything electrical worked as it was suppose to. I recall the wire being color coded and labeled every 6" as to where it went. I don't want to do it again, but it really wasn't that hard. Just take your time. I would buy that kit again. Best wishes with yours, Carmine.
