Rewired Fog lights
1 - 20 of 29 Posts
I have been wondering about this over a year ago...I asked the guy that did my remote start (he wks for the dealer) he said that the electrical system on the FX is a pain if you make a mistake you could cause a bunch of problems..So I still have mine the same way.
Isn't someone on the list an installer...he just was talking about alarms grtpumpkin i think..maybe he can help..

Looks like the fog light relay is controlled by the CAN data bus. So, looking at the manual, there are 2 ways of doing this.
First, looks like you can use the output from the foglight switch, and use it to turn on the foglamp relay directly, bypassing the BCM. The relay socket wiring is probably difficult to access though.
Or you could take the foglamp switch output, and run it to your own relay. Then cut and hook the white from the right and light blue from the left fog light to the +12 volt output of the relay.
Now I have not checked this info in my FX, but according to the manual diagrams and my experience, these should work. Unfortunately the manual does not state which wire at the combination switch is the foglight circuit. But they all seem to switch only 6 volts, so that may not be enough to trigger a relay. In that case there is a device called a LVT, or Low Voltage Trigger by Peripheral Electronics that would convert that 6v trigger to a 12 volt trigger.

This is just a question and not a critism...Why do folks have their fogs on in perfectly clear night driving...I have observed this since the advent of factory fogs.I have always run higher power bulbs and wiring,on the FX started with 6oook and went to 8000K and love them and never use fogs and almost never use highs!
After my last back surgery and I could not drive for 4 weeks ,my brother and son would both use the fogs with the lows..just cause we do! Any better clarity on this out there?

I don't get it either. Is it just to feel cool? If so, that's OK with me since other people's fogs don't bother me, but is there a practical reason for this?brnjugfx45 said:

I think it's just for looks, kinda like people swaping their fog bulbs for something that matches the HIDs; looks good, but not practical for what the fog lights are actually intended for: FOG. I replaced my fog bulbs with PIAA Ion Yellow bulbs and only run them when it's foggy; they are very effective.

I have to disagree on both counts. Fog lights are not intended to be used alone in foggy conditions with no headlights (at least not ones found as OEM equipement on today's cars). If that were the case, they'd be wired that way to begin with. They put extra light low where you need it in fog and if glare from the headlights even on low beam is a problem, we have the added benefit of being able to adjust our headlights down quite a bit. As for dark country roads, fog lights won't do squat; that's what driving lights are for. They are intended to throw light further straight down the road than your headlights.magician said:
How many people interested in this thread are in it for practical purposes? Likely not many; they just want to drive around with only their fogs on and look cool.
Where is the schematic for the parking light circuit? I want to jumper the two fog lights over to the parking lights. I plan on using the parking light power to switch the fog lights.gtxjoe said:Let us know if you get anywhere

I used the following link to redo the lights on my PGT

Here is the schematics for the from parking/front marker lights
I looked at the ford probe webpage, and the probe does not use the CAN bus to control the lights, so all that is involved in getting the foglights powered is some rewiring, and you can use still use the original fog light control.
With the FX, all the lights are controlled by CAN messages, so the hack will won't be as easy. I don't know if you can retain the use of the stock fog light switch. Let us know...
