> GW wire with male coupling -- nowhere to plug it in
Green with a white tracer is the RH turn and hazard lamps.
> PG wire with male coupling -- nowhere to plug it in
Can't find a purple with a green tracer, but green with a purple tracer is
the brake lights. Alternatively light-green with a purple tracer is the
hazard flasher to tell-tale wire.
> GR wire leads to large plug that plugs into hazard switch
Green with a red tracer is the left-hand turn/flasher lights.
> Confusion:

The in-line fuse for the hazard flasher feeds 12v to it and should be brown
both sides of the fuse. Be aware that the feed for the turn flasher goes
via the hazard switch in the off position. Sometimes the grease in the
little-used hazard switch gets very stiff and insulates the contacts. It is
possible to dismantle the switch (in a clear poly bag to catch all the
bits), clean and reassemble it. Sometimes flicking it on and off rapidly
several times can get some function back.

As stated above the leading end of the top two fuses should be linked
together and have a red/green from the main lighting switch. You should
have brown (front) and purple (back) on the bottom fuse, and white (front)
and green (back) on the second fuse up. The bottom fuse feeds permanently
fused things like interior lights and horns, the 2nd fuse up feeds things
like instruments, turn signals, brake lights, reverse lights etc. The
trailing ends of the top two fuses should have four reds on them, two on
each. One red wire from each fuse goes to the front, the other goes to the
back, via the mass of bullets interconnecting the main and body/boot
harnesses near the junction of the firewall and RH inner wing.
> Finally all dash lights are out.
As above, a red/green comes from the main lighting switch in the first and
second positions to the rheostat, then red/white goes from the rheostat to
each panel lamp. The gauges should have a black (ground) secured under the
U-clamp fixing nut or they may not light. It is not uncommon for the
rheostat to be burned out.
