Today I finished making an entire new wire loom for the rear tail/brake light and indicators, along with replacing the small and poorly installed aftermarket LED ones (that I assume the previous owner bought on ebay), to the original OEM tail light box unit.
I had to rewire and made my own 5 wire loom myself because the wiring was rubbing against the rear tyre as it was poorly fitted when whoever did the "mods" refitted everything.
It turned out, once I opened up all the horrible, sticky, gooey mess of electrical tape that one of the reasons the wires were making contact with the tyre was that the loom was thicker than OEM. The reason why is because they ran the wires from the back of the bike where the original OEM indicators go, all the way back up and around the rear guard, to where they mounted the aftermarket indicators under the seat.
This basically made the loom almost twice as thick as it should be.
The plugs on the loom were non-existent too. So there was no way of plugging the new light assembly into the existing loom. Bare wires, twisted together, wrapped in electrical tape. No solder, no crimps, no clips, no cable ties. Nothing that would resemble any logical repair or modification.
So I decided to cut five 1m long strips of automotive wire, fit two 6-pin deutche connectors to either ends. Colour coding the wires (Red, Brown, Green, Blue, Black) and using those colours to connect the two indicators, tail light and brake light to ground (black wire).
Everything was then heatshinked so its quite tidy and smaller than OEM. Being about to tuck itself right up against the rear guard. I used double walled heatshrink so it is quite stiff too.
I crimped all grounds (each rear indicator and tail/brake light) together (black wire). Red wire went to tail light power, blue wire went to brake light power, brown and green are to their respective indicators.
Now, everything works again, and is hopefully safe and a few more millimetres away from that rear tyre.
I also noticed that the rear tyre was fitted back to front on the rear rim. Again, the poor workmanship of the previous owner or the shop they were taking the bike to. Either way. The only thing now left to do is await the full lock kit with two brand new keys and finish off the restoration of this beauty.
Here are some before and after shots of the loom.
