Rear fog Lights

[pezzer]

Hi guys, can anyone help with regard the rear fog lights. I have no power to the switch where is it energised from. on the switch plug there is :1 Blue/Red which I believe is the feed to the lights, 1 Red/Yellow which I guess is the main feed to the switch as it loops to the switch lamp, and finally a Black which is the earth for the switch lamp.

Whilst I am here the wiring on the back of the fuel sender : 1 live light green wire to one contact , 1 green/black to the second terminal, is this correct as my tank level is not indicated.

Many Thanks Perry

Sounds like you might have a wire missing but remember that the rear fogs are only energized when the lights are on.

Regarding the fuel gauge it should need only 2 wires as the sender is a rheostat and the gauge is, I think, a voltmeter.
