I've seen lots of post but no answer to my problem. I have a 2009 XLT that didn't come with factory fog lights. Pig tails were there so I figured it's an easy fix. Ordered factory fog lights, new pull headlight/fog light switch and relay. Installed the lights relay and switch. Headlights and parking lights all work but no fog lights. 20A relay in Battery Junction box and 15a mini in slot 31. What am I missing? The dash warning light doesn't light up to say fogs are on. Anyone know what wires go to the switch to control the fogs? I guess it is possible the front half BJB foward to pigtails is wired but not the back half. It doesn't make sense since the switch is all one unit now. Any help would be appreicated. I don't want to add an after market switch like to stay factory.

Thanks

 

You have to have the computer reprogrammed for the fog light. Local dealer cost $120

 

Leave it to FORD to figure out a way to get more money for something that is already installed; that sucks.
if the harness was there you would think it would only have been a matter of plugging things in.

 

That's what I thought, bought the lights, relay, fuse and switch. I can read Ohms across the wires at the fog lights which tells me the circuit is good. Other people say that's crap but the dealer said different. If I had a different solution I'd try it but it looks like I'll be out the extra cash for something I thought would be a simple fix.

 

So it is working now ?

if not consider a rewire job.

 

I haven't taken it to the dealer yet. I'm still looking for a cheaper soultion. I want to keep everything factory I should have just gotten a truck with fog lights.

 

OK me too, to some degree.
Can you ring out the fog light switch and determine if it has wiring to adapt to another relay, say one power wire in and one out.
Then you can either find the OEM relay position and wire the switch and the relay according ly or buy an extra automotive relay and wire it to the OEM switch.
it works out easily, fuse panel to switch to relay, then battery to fuse to relay to lights.
think it over, to me having Ford do it will work but you will always be going bak to them.

IMHO… just drop the wiring from the OEM Sw and wire up a new rely and circuit.
