Our Vendor "Lights" sells pre-made looms. They really do make them a Plug and Play job. If your just starting out and have no real idea then i'd point you at a premed loom too to be honest. I had tolerant the hard way as there was no such thing as a Pre-made then but if there was i probably would have done that.

To answer your other question about your fog lights going to the same switch? yes they can but why do you want to do that? aren't they for 2 different applications? Lets face it your ignition is 1 Switch that turns on your whole car so a single switch is easily managed but you need to be clear on what you want it to do and that will determine how best to wire it up.
