    You need to buy a factory switch with the fog light setting. Yours won't work for this.

It's not a great video and he doesn't show much about the switch so people have to figure it out for themselves. But if he is right, it's a much cleaner way than installing ugly aftermarket switches and miles of wire......

    So you don't really need anything more than a jumper wire from what it sounds like. Doesn't really get any easier than that.

    The factory switch with fog light function and a jumper wire that goes from the switch to the relay. And possibly the relay itself. And also the factory fog lights with the bracket/plate/holder/thing

    The BCM is located behind the glovebox, about mid-level to the footwell. Forget about a flash...it will not work. There are several colored plugs that terminate there. I think for 2014 cars, it's a blue plug. I simply cut and soldered the two wires and bypassed the BCM. Note that the wiring diagrams call it something a bit different, so I tested it before cutting. Works a treat and is a super-clean fix, but the fog lights will come on even if the car is shut off. If you have a 2014 car, I can scan the relevant section for you.

    I'm planning on doing this when I get some free time. Here is some pertinent info. And yes, pin 14 on C2280D is mis-labeled according to the drawing. Obviously, you won't get the indication on the ipc with this mod either.

    the switch listed above is for vehicles that have autolamps. If your fiesta doesn't you'll need a different part number. D2BZ-11654-B. I recommend buying from Sunrise Ford parts because they have free shipping.

    I don't know if I will have the time. If I do I'll be happy to.

    Got this finished yesterday. I bought this fog light kit but only used the fog lights and bezels. The bezels don't fit the best but I'll eventually get some oem ones.

    I originally tried to unpin the wires from each connector but with the limited space I decided against that. I left about 1.5 inches of wire sticking out from each connector ( always have a plan b!). Unwrapped the harness to get some length and freed both wires. Re-wrapped both harnesses and then connected the two wires. I am well aware that soldering would be best but with the cramped conditioning and my aching back and knees, I used an uninsulated butt splice. Also I did verify that socket 14 on the blue connector (C2280D) does go to the - side of the fog light relay in the BJB (battery junction box).

    I'm very pleased with the results. The H11 bulbs in the fogs really do add to the overall lighting. Hope this is helpful to someone!

    Here's some pics from the install:
