Hi, me again, thanks for all the help so far.
This one is for the electrically minded amongst you
Lights and horn now working...

I have a 2 pole relay for the indicators, with B and L markings.
As I understand it, B is the battery feed and L the load from the switch.
The handbook wiring diagram shows these as black and green respectively.
I have these from the loom, although the green wire is about 2" shorter than the black and doesn't seem long enough to comfortably reach the relay and I also seem to have a spare white wire, same length as the black one and I can't see where this would connect
Any ideas on this?
