I'm doing the main light etc loom atm, left side as you look from the front. Its a fecking mess now to be honest and I'm getting the the point that I want/need to pay someone (who?, I have no idea!) to finish it as its holding everything up.
The old wires won't take solder no matter how hot I get them, lol the bloody insulation melts off the wires before the solder!
I think the way to go would be a fusebox back re-wire but thats more involved than I wanted to go
The only part of mine which is complete and I have confidence in is my fuel rail loom (efi) thats mint but only 20% of the job. Not complete in the pic below (is now though) but you get the idea, new lol
