In a 2006 XF95/430 there is a accessory (■■■) lighter to the right of the centre console marked 24v. Plus another, not marked , on the left of the console along with a smaller socket. Are the ones on the left 12 or 24v?
Dont tell me to do something inspirational like use a voltmeter, as I’m at home & the trucks at work !
If you take the dash out there is a spare 3 pin plastic block connector directly behind the radio, this is 12volt, just run a couple of wires and connect a plug and you have a 12v system, the cig lighter and hella plugs on the lhs and under the seat are both 24v.
