Title: Indicator relay wiring
Post by: Johny Boy on April 10, 2026, 10:21:55 AM
Hi, me again, thanks for all the help so far.

This one is for the electrically minded amongst you

Lights and horn now working... ;D

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?

Nooooo!!!
Black is power, grey is load to switch, green is earth for the original 3 pin relay
