This has prob been asked before but is it simple to add fog lights as mine dont have any. would i just need the switch or will i need to wire them in also etc?

What car is it bud?

sorry for adding in but I'm looking for the same thing, for my 6n, I've got a fog switch, got fogs and grills, i just want to know what wiring i need to get them working.

cheers

There is a guide in the faq section. Basically if you want them to have oe wiring, then follow the guide and connect to the round connector near the radiator. Or if you want to run a relayed setup, which will be better in the long run and give much better output, then connect puns 85 and 86 on the relay to the two pins at the round connector (shown in the guide) and pin 15 to the battery with an Inline fuse and pin 30 to the fogs then ground the other wire at either the threaded posts on the chassies legs, or at the base of the battery.
