I didn't want to pay $400 to the dealer to install factory fog lights - bought the parts and installed the lights, headlight switch and relay, but they will not come one. There is power to the fuse, if you jump it, the lights work, but not to the relay. Does anyone know if there is a missing wire from the power box to the headlight switch (the other wiring from the lights to the box was there) or if the computer has to be reprogramed to tell the truck that it now has fig lights?

 

went threw the same thing this weekend no power at the lamp plug at the fog lamp plug.New fog lamp switch pull fog lamp headlamp power on power at the fuze box in the engine compt?????.
some help us out.

 

Mounting of the light is very straight forward....you're already setup for it. Just get '08+ foglights for your 08+ truck, then bolt 'em in.

I suggest wiring them stand-alone, independant of the factory wiring utilizing an aftermarket switch. Wiring diagrams can be found here in the tech/electrical section and possibly in the how-to section as well. Remember to use a relay and fuses. The BS with making it work and having to get a new headlight switch w/built in fog switch just seems too darn expensive to me.


You must have an XL right? Because I believe all '09+ XLT's have foglights standard.

 

the new headlamp switch w fog lamps was only 23.00 from rock auto still in the ford box.

 

Not sure if you got this done yet but I read in another thread that the computer needs to be reprogramed (?), not sure funny though.

 

Yeh i read that also, bet thats the problem. Although its got to be one of the dumbest ideas i have ever heard.

 

Why not just rerun some wires.
I know you want to keep thing OEM, me too, but sometime you just can’t and $120 worth of can’t is s lot to throw at the Stealership.
Ring out the Switch and if you know the correct relay position, determine the pin out and the wires.
Trace the wire to determine if you can use them and then add a relay and some wiring where needed, apply power to the new circuit and Wham Bam you got it.
OR
add a whole new circuit with new relay and all and use the exisitng switch, clean up the wiring to look OEM and you have the circuit and YOU know the circuit and it didn’t cost more than $15.

Luck

 

Hello, I know you guys have probably figured out how to do this by now, but here is my story with this fog lights issue. I've installed fog lights on my 09 ranger. Took about 5 hrs because I took my time. I purchased a factory style switch with the fog light option from ebay, about $43. The OE style fog lights was less than $60, but I don't remember exactly. Anyway, you have to remove the radio bezel, the hood release cable, the lower dash cover, the metal plate under it, and the cover around the light switch and gauges. You don't have to take it all the way off. Careful, there are little rubber bumps on the backside of that cover that are easy to break off. Then you can access and disconnect the switch. Install new switch. Probe pins with tester to find wire that is hot when the switch is in the fog light "on" position. If I remember correctly it's violet/white. From that wire I ran a 14 gauge wire through a grommet under the dash to the engine compartment to my relay I installed in an empty space in the junction (fuse) box. I found a relay diagram for this setup online (see attachment). The factory fog light wiring pigtails are tucked away above the fog light openings. I cut the wires about 8 inches from the pigtail and connected my wires from the relay to them. I grounded the brown/yellow wire on the pigtail to a screw directly above the fog lights. Everything looks neat and "factory". Wasn't really that hard, just take your time. Be sure to use fuses at the power wire (20-30A) and at the wire going through to the switch (3A). I didn't want to mess with the wiring in the Junction box so this is how I did it, and it works perfect. Good luck.

 

Hey! I know this is an old thread but I figured it out. All you have to do is get FORScan, read your truck's computer, and change one of its runtime variables to enable the fogs. I'll be writing up my full findings soon, once I actually get the fogs for my truck, but the variable in mine was in the GEM/SJB. I changed 726-01-1 5200 0000 0081 to 726-01-1 5600 0000 0085 and the switch started working, the dash indicator came on, and the relay I put in the engine bay started clicking.
