I've seen similar mods for the fog lights, but I haven't seen any where you can turn the fog lighs on whenever you want. If somebody has already posted this, then forgive me.
I wanted to be able to turn my fog lights on anytime that the ignition is on, so that you don't have to have any marker or headlights on. And you can still turn them on and off with the stock switch in the dash. So if you leave the button ON the fog lights will come on whenever the truck is on, just like daytime running lights. And they will shut off automatically whenever you turn the ignition off. To do it I just pulled the fog light relay out and bent the top-right terminal over, so I could fit a female spade connector to it. This is the connection that tells the relay to turn on. You can use a small wire because very low current is required. I pulled the ignition fuse and soldered a small 26 guage wire to the inside edge of the fuse blade. I pushed the spade connector onto the relay terminal and then stuck the fuse back in. Works like a charm!
If you put a fuse inline, use a 5 amp fuse, so that it will blow in case the fog light relay ever shorts out. The red ignition fuse is 10 amps, so the 5 amp fuse should blow first, which will make your fog lights go out, but the 10 amp fuse will be OK, and your engine will still be running.
This is an old post, but I'm bumping it up because a couple people have asked me about it.
Also wanted to let you know: That red fuse in the picture above is connected to an ignition circuit that turns on and off when the truck turns on and off, but it can also come on by itself sometimes. About 4 hours after you turn you truck off, part of the ignition system turns on for a few minutes. I think it has something to do with controlling emission fumes that build up in the gas tank. So 4 hours after turning my Taco off the lights will turn on for a couple minutes. Unless I turn the fog light switch off inside cab. It's no big deal, but it was weird when I saw the lights come on by themselves. It won't drain your battery or anything. They only stay on for a minute or two.
If you don't like this, there is another ignition circuit that you can tap into, in the fuse panel under the dash behind the drop door by the drivers left knee.
Anybody, let me know if you were able to find a circuit in the under-hood fuse box that doesn't do this.
PBmAX, sweet ride- how do you like those PIAA SuperPlasma's, Ive been looking but not sure which ones to buy, the whiter and brighter the better, ebay has several different ones, I wonder if 5000K is enough light, they go all the way up to 12000K (K=Kelvin rateing). thanks

I lost the picture I took but I followed Gargoyles rightup but just connected 2 wires on the underneath side of the fuse block together with a quick splice. Its all hidden under the fuse block and I can use the Fogs anytime.

I didn't think of that. What color wires are they? Do your lights come on every 4 hours like I expained earlier?

I love the Super Plasmas. Much better than stock, and pretty easy to install. The Tacoma manual has details on how to properly change the light bulbs. The passenger side is the hardest to replace because of the window washer fluid tank. Just be sure not to touch the bulb. Or you can wear rubber gloves when you're installing them. The fog lights are super easy to replace. The PIAA fog light bulbs come with 2 different o-rings you can use. Take the thick black o-ring off and replace it with the thinner red one before you install them.
I think I got 5k or 6k. They are plenty bright enough. Check this post for more info.
Just wondering, has anyone looked to see if there is an Auxilary fuse where you can switch the fog lights up to as if you were installing it indepently.

Every fuse on the fuse panel is powering something. I don't think there are any auxilary fuse spots that are sitting there un-used, but there are some un-used spots and terminals.
On my truck, in the in-cab fuse panel under the dash, there is an empty spot in the middle of the panel. The bottom terminal goes on and off with the ignition. You could tap into the terminals with a male spade connector, but I would probably run that to a relay, as I am not sure that, that circuit is big enough to handle powering the fog lights by itself. You'd have to add an inline fuse somewhere too.
