I closed the other 2 threads because we have similar topics where we could take care of them all in one. My appologies if it didn't sit well with you.

If the dealer mounts the lights and leaves the rest to you, you probably only have 1 hour left worth of install. A relay, wiring, zip ties, a modular switch that allows you to turn on the fogs at any time and you're done. The firewall opening is extremely convenient.

Get the lights you really want. Make sure they float your boat since you are getting a custom install. Note, the lamps and their ratings usually make a big difference. If you go above 55W, then you will only be able to use them offroad. At that point, make sure you have glass covers or you run the risk of melting them.

If you need more help with the electrical schematics I am sure you can find them here on XOC. The relay approach is the only way to go, and once you figure out the 87, 88, etc. meanings they are simple.

Additional fog comments should continue in this thread, otherwise when people search "fog lights" they are going to get a plethora of hits. Not a good thing.
