So I have been wanting to replace my existing wiring harness with a completely new loom that I'd be putting together myself. Besides a non functioning electric starter, my electrical seems to be fine. However, since the bike is nearly 40 years old, I figured it's best just to put together a new loom with new connectors and wires all around. This would be a project I could do inside over winter. Because I didn't want to get myself into a pickle, I figured I'd purchase a used on on eBay and use it as a reference. That way I can keep the existing harness on the bike and once complete, I can just swap out new for the old. Any problems with this approach? Besides the cost of the additional eBay harness?
