Recently, I stuck some 35 watt HIDs into the grille fogs on my '12. The annoying thing remains the shutoff of the fogs when the highs go on. So I started poking around and the only solution thus far required alot of cutting of wires and relay crap to the SJB in the interior.

Figuring there had to be an easier way, I tapped battery positive to the input positive for my HIDs and et voila, fogs stay on...all the time and don't respond to the switch anymore. :bad:

Now, I could just tap a switched source underhood and call it done but, that leaves the fogs on all the time and they are pretty too bright for that.

So, simple, SPST switch unobtrusively buried in the interior, hooked up to 12v + battery (if you can remember to turn it off when you leave the car) or switched 12v + if you can't, tapped into one side of the lamp power and, done. Fogs + highs when you want them, and a simple 2 wire loom to hide underhood. :good:

i use to run to my ambers for my 35w fogs without issues...plenty of power to supply them and the only time they turn off is when the headlights are off...however since upgrading to 55w i had to run a hard line to a switch, but with the location i put the thing i won't forget to flip it at least lol

Big for me was finding a way around that didn't involve invading the extant wiring on the car. This accomplishes that without any risk to any expensive feedback smart parts.

I need switchability, these things are high and blazing and I need to be able to turn them off in the city. Hence a simple on-off switch to the piggy-back power source makes that possible.

It's not legal to have that many forward facing headlights on at once, that's why ford didn't make it easy. I assume you are doing this for better illumination outside city limits?

Legality depends on locality....and your local plod. I have 6 forward facing accessory lights on my truck, plus the two headlights, no issues.

However, I am considerate of other drivers and only run them in the back country.

Same with this, it's for help in poorly lit and lightly travelled areas. I won't turn them on in the city except as DRLs in broad daylight, as that's factory setup.

Ford has historically made it stupid easy to do this. Separate relay for switch off, simple jumper fix.

It's not legal here in Tx, but if you're on a backroad w/o any traffic nobody would know and that's where you'd want extra illumination. With just my factory fogs and low beams I get flashed occasionally. Highs and fogs is a different ball game

Job's done. I ran a tap to FL power and from an unused 30 amp slot in the fuse panel. Couldn't find a switched source that I could be sure of the amperage on so 12v unswitched it is. Ran the wires neatly in a loom around the bay, in through the hole where the sound tube once resided, to an unobtrusive switch mounted under dash near the OBD2 port. Switch off, lights work as factory, switch on and lights stay on with high beams and they get voltage hot from a source capable of supporting 30 amps, so way overkill for 35w HIDs.

Basically you fire up the factory HID headlight on bright and the fogs this way and it looks like the car's nose is made of burning magnesium. :D
