I am writing this before cracking my shower beer, but, after ~1 year and a few weeks, I have finished the bulk of my wiring harness replacement. I started it about a week and a half before my son was born, so it took a back seat, until he was more independent in play and care. I still have a few odds and ends (new neutral safety switch, heater fan wiring, and adding new LED tail lights), but it's essentially done. Before getting it back on the road, I want to drop both tanks (have the hoses and necks for them, and clean them out, since it's been sitting for a year. Otherwise, I'll be getting started on the body/hardtop, before overhauling suspension and updating brakes.
I can't put words to what a relief this is and the excitement of no longer chasing electrical demons from the PO's awful repairs. Cheers to a great weekend!
