I would recommend Classic Parts original type wiring harness for any electrical novice, like myself. Having never done anything like this before, I was really impressed how the wires were the correct length, connectors attached, and already inside insulators usually. It was pretty basic. No wiring included for deluxe heater, accessory juntion block, taillight pigtails, or turn signal switch. I'm about 1/2 way done. Problem is when the old wiring got torn out, I saw about 20 little jobs that needed done before wiring it!
