I've been trying to track this down ever since toxarch started his Fog light install and EUREKA! I've hit paydirt!

So if I read that right, the factory fog lights are set to switch on any time the tail lights are turned on? I thought that the factory fog lights were wired to only come on when the head lights were on.

I'm trying to see if there is a way to wire the lights in with a factory look. The fuse box has a place for the fog light relay already wired and has fuses already in place for them. I'm still planning it so bear with me. And thank you Squid for looking that up and sharing what you can with me. Wiring it up after market style would be simple but I want to try the stock look first.

Looks like the fogs can be turned on as long as the tail lamps are on (if I am reading the schematic properly). Strange way to do it but, I don't see a problem with the logic.

With the proper components, can the fog lights OEM switches, etc. be installed, without changes to the wiring harness.

In other words can I plug in and go, once i did out the correct connectors on the wiring harness.

Thanks, Dan

From what I have read and seen, as long as your truck is wired for fog lights, then you should be able to plug and go with factory parts. People had previously said the factory setup was close to $700. Now I have read some saying they've found it for close to $300.

I just posted the pictures of my fog lights. see here: http://www.toyotatundraforum.com/pho...500/ppuser/138

The best way to install fog lights is a combination of the OEM switch and after market lights and relay. The switch cost me about $90 at the dealer, the fog lights are KC HiLighters-100w fog, black chrome at about $80/pair, and a relay from AutoZone (part #41-5154)for about $22. One note, the OEM relay goes for about $70, and I could find one on the internet for $5, but there was a minimum order, and shipping costs.

Total cost about $200, and total time about 4 hours, most of which was drinking a beer or two and figuring out how to mount the lights.

I saw some very nice projector fog lights on some type of Chevy SUV... Looking everywhere to see if I can find a set after market. Will the wiring be the same for such an item?

You should be able to adapt it to the Tundra, you may have to find a friend that understands wiring diagrams and has a meter so they can make sure that power and ground go where they belong but electricity is electricity even on the Big 3 vehicles.

I've gotta get some, I can't stand not having any......

I agree - I am wanting fog lights too for my truck. Any word on OEM and the price?
