fog wiring?

[twiss]

I was lazy with my foglight. It didnt work through the fusebox so I put an inline fuse in dash and just wired straight from the switch to the battery. Only time I use it is when the MOT comes round anyway

Mine's an LED one as well so it should never be drawing a massive amount of amps

just been for a look, i have 2x grey/green trace wires coming from 1 spade on the switch and one grey/green trace by the lights. So put that to my fog job done?

Probably not that easy, That may well be the switched live for the foglight.
The earth wire for the fog light comes from the headlight switch.
If you earthed it direct it will work any time the fog light switch is operated and I would assume this is not correct for the MOT.

Just tried connecting the grey/green trace with no joy. However i can only turm the side lights on currently. TRhere is aslo a red/white trace that is next to the grey green on the switch that is running back to the rear also.

I will have a play tomorrow


EDIT



got that working, but when it is turned on, the heated rear windscreen light comes on the dash instead of fog...



help

Have you connected the grey/green (suspected switched live) to the foglight and connected the red to the foglight. A red wire would normally go to the demister element. However if connected to the foglight this will create an earth path though the demister warning light and therefore both the foglight and demister lights will come on.
Leave the grey/green connected and just earth the other foglight wire and see what you get.
