Mike,
All original. I replaced a lot of the wrapping with friction tape. I went through all the connections with electrical contact cleaner, and 400 grit wet-dry paper and rotary tool. Blew everything dry and applied a very small amount of dielectric grease in the fittings after popping them in and out several times to be sure the contact points were clean. Any connectors or connections that were questionable, I replaced or repaired. Bench tested everything I could. Not a fun job. I spent lots of hours on that loom and connecting harnesses. I also fished the main loom in-between the main backbone and lower support member to get it out of the way. I'm glad I spent the time for that - it enabled all the other wiring and cables to have plenty of room. I promised myself I would do whatever it takes to only deal with the electrics once. I'm an idiot with electrons. I just don't get it. I've never understood what I "can't' see. I'm learning more and more all the time.
