Tundra Fog Light Wiring Problem | Toyota Tundra Forums Aug 11, 2017Hoping someone can help. Have a 2007 tundra with pre-wired fog lights to front of truck. Bought after market kit and tried to follow forum suggestions. Tapped red wire to green parking lights and black-white wire from switch into light blue wire. My switch did not have a darker blue wire.

OEM Fog Light Installation - Toyota Tundra Forums Aug 16, 2011Got my fog light kit today and looking at the truck this may be a bit of a project, however something interesting is that it appears the wiring for the lights may already be there and all I really need is the relay in the fuse/relay box for the fogs and the switch. I have the switch from the kit, but not a relay that would fit the socket.
