    I was wondering if anyone knows a website where i can get instructions on how to make it so i can have my fog lights on when ever i want. They turn off when my high beems go on obviously.

    According to the electrical/wireing diagrams for the Tacoma fogs, they get positive power from the right side headlight.

    This means they can only be turned on when the low beams are turned on.
    They turn off when the the high beams are turned on.
    And they auto turn off if the lights are left on and the key is removed.

    To bypass this, you will have to run a seperate switched power lead from
    the cab to the power side of the fogs thus bypassing the headlight switch.
    This is how I plan to wire up my fog kit.

    WARNING! Bypassing the headlight switch disables the auto power off if you leave them on and remove the key.
    Althought, if you use a switched source for the power, they will still turn off with the key, not the body ECU after 10 mins.

    When you do this, would you mind documenting it with pictures? I would love to add fog lights to my truck, but I am waying the options of the "how" to do it.

    Cheers!

    No problem, I'm doing that now. :)

    As suspected, the 2.7L 4-cyls do not come pre-wired for fogs.

    I "thought" I found what would have been the fog light pigtails but after closer inspection, the 2 bolts holding the pigtail made me think otherwise. I'm pretty sure what I "thought" was unused fog light connections was indeed the sensors for triggering the air bags. DON'T TOUCH!

    I removed the small flip down cubby on the left side of the steering wheel which turns out to be the cab fuse box. I did find an unsed black plug with 4 wires right where the fog light switch would mount. However, I dont believe that is what this plug if for, the wires are very light weight. But on this plug I did find two wires Im looking for to iliuminate and dim the new fog switch once I get it installed.

    Any guess what this black plug with 4 wires would be for if equiped in a 2.7L??
    I'll seach the wireing diagrams and see what it might be.:cool:

    I have no idea what those 4 wires are for. Good luck with your search.

    Its DONE! Now have Fogs in my 2.7L Access Cab. :thumbsup::humble:

    After spending many hours taking apart my dash looking for instrument wires to illuminate the switch, and a switched power soure of proper size, I gave up and followed the wireing diangram from the CD-ROM version of the Tacoma manuel I got off another web site, with the exception I used the parking lights possative power on the magnet side of the relay.

    Someone else posted they did the same thing with their kit, so I guess I copied that install.

    I'll write something off line then post it up and completed.

    Heres some pics to wet your appitites. :)
