Who restores wiring harness

Pretty sure that Year One gets their harnesses from M&H since I bought several from a liquidator on ebay. It had both labels. Year One will add delays and probably a mark-up. Those were for later 1970's cars, so I ended up not using and flipped them for a nice profit (~$60 bought, $~260 sold I recall). People were fighting for it, probably because lead times are usually months when you order.

But, first check your harness closely. It gets very hot here but all my under-dash wires were fine other than hacks by gomers that I cleaned up. The vinyl wrap might just be dusty so try washing it first. I took all the vinyl wrap off to inspect and repair. For re-install, I bundled w/ nylon ties and covered w/ PVC sheath and split loom, but would also look slick w/ plastic mesh like used in high-tech stuff (expands like a Chinese finger puzzle).
