My son and I are trying to resurrect some sun-baked SunL quads. We got the battery charged and the starter turned over, but as I began to troubleshoot the lack of spark (which I have seen a couple other discussions about) one of the connectors just crumbled in my hand. I tried to repair it but the wiring is completely dry rotted. So... Easy solution right? New wire harness. Except.... Nobody seems to have the harness for this guy.

Any advice as to vendors, or alternatives (is: try a Honda harness) etc...?

Thanks!
