My Vitzes headlight switch was malfunctioning (the parking lights didnt go off) the switch seemed to have got stuck. So i sourced a new headlight assembly unit from the scrap. (sheirshah) Now the stick i purchased has a fog light button on it like the cars with factory fitted fog lamps do.
The assembly was clip to clip fit no changes what so ever, My mechanic told me a complete grip to grip wiring would need to be purchased to get it working let it be as it is.
Any one with a good electritian or a wiring diagram to get it working. Currently my cars fog lamps are directly connected with the parking light wires no extra button.
