I need the wiring diagram for a 2006 ford f150 xlt super crew headlight in order to wire oem fog light harness to headlight harness to get my fog lights to work.

Question edited for clarity.
Question moved to model category.

There is help in the link. It probably needs removing and taking to an audio tech.

First check to see if there is not a wire harness built in from the factory

Mike, Ford F150 relay for electric windows, position 401 in fuse box, some forums say Relay in position R02 may be tied in with pwr win., maybe check fuse 22 position also, actually for all the time it takes probe all the fuses with test light or DVOM, as Ford may have PWR window delay or something like that tied into another circuit. You may have a broken wire/ ground ,etc in the harness that runs through the door and pillar.

The Easiest Way is to Get the Wiring Harness Diagram with the Colors and Verify that you plugged the Fog Lights into the Correct Harness. I once had a FORD that had a Fuse BOX that had a FOG LIGHT and No Power to that Fuse.

Make sure you test the Fuse at the Box and then Trace the wires and if the Switch was wired at the Factory, you should be all set

There may be a connection in the harness or a place to connect the cabling, but what you'll find out is that the light switch is different for the trucks that have fog lights from the factory. They have a pull-to-activate function for the fog lights and an indicator led on the switch that shows the fogs are illuminated.
I would suggest purchasing an aftermarket fog lamp kit with the entire package...switch, wires, relay etc..cheaper in the long run... not too hard to wire on these either...the toughest part is feeding a wire thru the firewall... but even that's not too difficult.
Hope this helps...

This is a common problem on 97-00 MY trucks, regardless of the trim level ( XL, XLT, Lariat ).

If you install the fog lamp fuse in the BJB ( aka Battery Junction Box, Engine Compartment fuse panel ) Fuse # 9 ( 15 A fuse ) and jumper the normally open contacts in the fog lamp relay socket ( see diagram below ) the fog lamps should illuminate ( to confirm what you have doing on ).

The problem usually is the main headlamp switch to the BJB is not in place ( this is the yellow wire from the main headlamp switch connector to the relay socket pin #1 ).
One easy route is to make an aux lighting relay & harness, or purchase one online. With this, you can cut the factory ends and attach them to the harness you purchased. There is an air inlet next to where the steering wheel column runs through the firewall. This would give you an easy route to the fog lamp switch. The fog lamp switch, you can buy the factory one, and change the yellow wire from the connector to your added relay, or just add a switch for this function.
This will give you an idea of what the DIY relay and harness would look like.


Hope this helps, more than confuses at this point

Just contact your local dealer and ask them for instructions for the OEM fog lamps. I have ordered Honda fog lamps, and you can usually find a pdf document on line with detailed instructions. The nice thing about Honda accessories, is the harnesses will only plug in one way. Hope this helps

1. Disconnect the battery ground cable.
2. Depending on the year and model remove the wiper/washer and fog lamp switch knob if they will interfere with the headlight switch knob removal. Check the switch body (behind dash, see Step 3) for a release button. Press in on the button and remove the knob and shaft assembly. If not equipped with a release button, a hook tool may be necessary for knob removal.
3. Remove the steering column shrouds and cluster panel finish panel if they interfere with the required clearance for working behind the dash.
4. Unscrew the switch mounting nut from the front of the dash. Remove the switch from the back of the dash and disconnect the wiring harness.
5. Install in reverse order.

Good luck.....

Rusty Did you receive the diagrams I sent? Park lights and dash lights are on the same fuse and circuit.
