    Do you have a test light? Do you have power at the switch? Do you have power at the relay? Did you add the relay? If so, do you have power at the light(s)?

    Not really sure but here the part. Found it on an old message. As long as it's compatible it should work

    Well need more information.
    You say it was wired for it. But what fog lights are you installing?
    I’ve not seen any kit that doesn’t use a relay.
    Also, most aftermarket kits run power from the switch to relay.
    Toyota use the switch to ground the relay.
    If you are using the factory switch and wiring, this could be your problem.

    If you didn’t cut the factory connector off for the switch, get a factory switch and relay, also dis you use the factory connectors at the fogs? There really was no reason to remove any of the factory connectors if you did. There are plenty of switches and harness that plug and play the fogs if prewired.

    it’s a factory style fog light, but i only got the lights not a full full harness for it. i specifically ordered one that was made to be used with that factory wiring and i never removed/installed any connectors.

    If the wiring is all there.
    You need the switch, the relay, the lights, and the fog light fuse.
    Do you have these all installed?

    If you’re using the factory harness, you might have to have the headlights on to work the fogs.

    thanks to all of you guys i figured it out. in order for the fog lights to turn on yes the headlights do need to be on and it didn’t come with a relay. i got one put in and made sure all the wiring work and now my truck looks 10x better than before so thanks to all of you for helping. 675B4491-A8CE-4ECB-990E-919E00076401.jpg
