i noticed that the inside of the bumper looks like it is prewired on my car for the fog lights. I was cleaning my cold air intake in the front left of the bumper and saw it there. There looked as though the matching one on the other side too.

OEM foglights are plug and play. I don't have any foglights, but I have read that they are plug and play aslong as they are OEM.

The oem fogs are an easy install. Cut the bottom grill and mount lights. Plug into the wire you see inside the bumper. Pop the switch in the dash. Plug the wire hanging under the dash into the switch. Done!

You can go to TRD sparks and look up the fogs (or any other part). The pdf of the installation instructions is always in the upper right corner. It shows the wires in place on the xB. You don't even need the paper template to cut the grill. My grill had marks molded into it that show where to cut.

I would think you could buy the switch and use any fogs. The plugs may be different though.

Partially true. You can hardwire them all to the proper wires but you'll have to use a meter to figure out what wire does what. The benefit to factory is thats sorted out with the connections since there's only one way it will clip together. Also you might have to put a stronger fuse in the fuse box depending on wattage in the aftermarket lights. The only other thing I can think is Toyota likes to keep relays unless you need them. Not sure if there is already a relay in the fuse box for those lights but if its not, its a cheap part through toyota. The switch can be an aftermarket as well but you'll again have to figure out what wires do what. One will back light the switch, one's your hot and one's your accessory if I had to guess. Anyway, short story long, yes, you can run everything aftermarket if you want.

:cheers:

When I installed my aftermarket foglights into my 2011 I spliced into the factory harness wires that were already there. The white wire with black strip is ground but since I installed onto the factory grill the foglights are electrically isolated so +/- did not matter. I did not need a stronger fuse.

The only other thing I can think is Toyota likes to keep relays unless you need them. Not sure if there is already a relay in the fuse box for those lights but if its not, its a cheap part through toyota.
In my 2011 the relay was already installed. There is an audible click from the relay when I turn on my foglights.

The switch can be an aftermarket as well but you'll again have to figure out what wires do what. One will back light the switch, one's your hot and one's your accessory if I had to guess.
I went with the OEM switch since I read elsewhere that the OEM wiring to the switch is not what you'd expect. There are 4 wires. One is ground, one is backlight, but the other two are weird. One person wrote that he blew fuses and had other problems so I just bought an OEM foglight switch online for $51 shipped. The switch is a different size from other Toyota products and even different from the 1st gen xB. One advantage of using the OEM switch (besides plug and play) is that when the fogs are on, a foglight indicator lights up in the dash.

I did notice the OEM wires for the foglights are rather small and that makes me nervous to run the fogs for extended time periods. When I install my front lip in the future, I'm going to also add an aftermarket relay and heavier wiring for my foglights.

I don't mean to threadjack, but what upper grille do you have?

BrickPig, I figured they probably included the relay but sometimes they don't so that's good to know. Just for your understanding, the switch wires are (as you said) ground, backlight and two other wires. The two other wires are the hot wire and accessory wire. (one comes off the fuse block/battery, the other goes to the lights.)

i think the factory switch is $75 all by itself. Sam, do your fogs still dim on high beam?
yes they still dim. I basically just brought power to the relay on th fog light side to be able to power the fogs with just parking lights turned on.

I wish they'd stay on but i barely use my highs. Actually i dont think i have yet.

Just curious, how did you get power to the relay in order to be able to run the fogs with just the parking lights on...
