Hi everyone.
Can you tell me how are connected the wires for rear fog lights? In order to work it is neccesary to have the ignition on, the low beam on or something? The previous owner did a crappy job at the rear electric system, and 3 wires are hanging in the air.
Thanks.

are the lights earthed? maybe the loose wires are earths?


cheers

All the rest of the lights are working fine, but the fog ones...I don`t know what i must do to get "signal" on the wires, that`s why i asked what are the conditions - ignition on, low beam on. Of course, the switch is turned on, and it seems that is a relay connected to the switch wires (the relay is good).

Turn hedlights on full, ignition on, turn foglights on.

Take a bulb, ground the body of the bulb to metal in the boot, try each of your 3 wires on the + terminal of the bulb, when it lights up you have your fog wire.. make sure it is the fog wire by ensuring it doesnt come on with this wire when the foglight switch is turned off.



if it doesn't work.. run a wire from the foglight relay/switch output direct to the bulb holder.
