MichelvdM Posted October 12, 2013 Share Posted October 12, 2013 I have purchased an original Lucas rear fog light switch to be used in my 1500 Spitfire. Unfortunately the wiring loom isn't prepared for this switch. Can someone help and explain how I should connect the wires? Colors are green, black and white/black.Thanks and regards,Michel Quote Link to comment Share on other sites More sharing options...

Bainzy Posted October 13, 2013 Share Posted October 13, 2013 If your loom is original, there might be a pair of wires already in it for the switch (but not the full loom). Mine never had fog lights but it has the two wires that run from the boot all the way to the fuse box, at which point the fog light loom would attach. Think one of them is blue/red and can't remember what the other is. Obviously that doesn't help connect the switch up but makes life a little easier if you have them.

I know there is a brown wire going to the light switch. Can I use this one to connect a wire to nr 30 of the relay?What if I also want to use a relay for the main lights? Can I take the brown wire and connect this one to number 30 connections of both relays.Also, I have a clock mounted in the dash. Can I also use the brown wire for this?Thanks,Michel Quote Link to comment Share on other sites More sharing options...
