Re: Baffled x2

The indicators are AC from the reg, and the flasher relay works front/back rather than side/side from what's on the wiring diagram. Yes that's correct, front/back. not side/side :oops: If the rears have been wired to the fronts, then that can stop the headset indicator from working. Changing the wi...

Re: Baffled x2

Those extra wires are normally for the PRD relay, which has probably been removed.

Grey is normally AC power and black earth, so plugging them together will short all electrics out.
