I done a partial rewire on my last 90, well....both front light looms & the whole rear end I used twin core red n black but used the
correct coloured insulating tape so when I sold it & anyone had to open up the loom they would know how it was wired.
I also ran all the earths back to the battery & used another earth to the chassis. That was a pain but much better than the cr@ppy
earths from the lights to body that always fail.
Anyhow wots the D2 like I was looking for another disco.
For new looms see here.............
