cigarette lighter wires?

[young-saxo]

the three wires that are connected to my cig lighter are yellow, blue and grey.

could sum1 tell me please which one is which one basically. thnx.

yellow could be earth... blue is live and grey could be neutral...
im not sure just my guess...

[stendog]

yellow is earth, then blue and grey are both 12V but one is 12V with lights on i think mate. not 100% sure though mate

[John]

yellow is normally live tbh

best thing to do is to get a multimeter on the wires to determine which is which

yellow/green is earth though

then you will have illumination/sidelights and finally a 12volt switched wire
