The engine harness was a no brainer. Replaced with M&H. For the front lighting harness I ordered the next size up wiring to reduce voltage drop and made it myself.
The dash and rear harnesses were in excellent condition but I still increased the size of the ignition wiring and starting circuit wires. Like Data, I inspected all the terminals and replaced those that appeared to be loose. Replaced some of the terminals in the fuse box and added a tab for the IGN opening in the event I ever need a full 12 volt ignition circuit.
