Does anyone know what size SWG Premier wiring use for the Ign switch circuits as i need to rewire mine?

ATB Dan.

Hi Dan, don't know what Premier use, but I would suggest that 1mm thin wall would be more than up to the job, (16.5 amps).
Thats what mine is wired in. HTH Ray

Vehicle wiring products have a 'what thickness of wire to use for what' guide on their website here

Cheers Chris, looks like 4mm2 is the smallest i can get away with, time to raid the work stores
