I'm in need of some help. I have a 2014 F150 FX4 that came with factory halogen headlights and I wanted the factory HID headlights instead. So I bought the headlights then soon found out that I needed a wiring harness to adapt to the new housing. That finally came in 2 months later and pumped to finally install the HIDs. So I have low beam HID but no high beam. I check for loose connections in the harness and can't seem to find anything. Then I check the fuses in the cab by the passengers feet and it seems I'm blowing the 15A fuse. So I tried a 20A and same thing... popped... tried a 30A and pop... I read the truck manual and it says that under the hoods fuse box there are HID fuses for each headlight. I tried to call 2 different Ford dealers and they had no clue what was going on so the took my name and number and haven't heard back. So I'm hoping that someone out there can help me before I go insane. Thank you very much.

I had this issue as well. Try checking your grounds. Once I fixed those on mine I never had an issue again. Also, not sure if you're engine is running when you are testing them but try that. Or even run the truck for a while. Maybe the system needs to learn they are there or something. Just throwing those ideas out there.

I've tried all those ideas. Tried another 30A fuse and that one held together but still no high beams. Maybe I'll try the grounds again after a bit.

Increasing the fuse size is very quick way to burn your truck to the ground.


You need to find out why you're grounding out the fuse.

You might have a bad harness or relay box. Talk to your supplier.

Yeah I've been trying to communicate with the supplier and it's a joke. They are the worst online business I've ever delt with. I've emailed them multiple times and nothing at all. I don't think they are grounding out as you say or just to much of an inrush current. There is 2 sets of fuses. The ones that are under the hood for HID are missing so not sure about that as I have also installed those fuses and still nothing. But I'll keep trying and thanks for your help.

If you didnt have factory HID's, your truck's wiring most likely wouldn't have the HID fuses in them, which is why that isn't helping.

Also, if your harness is working correctly, it should put almost zero load on the stock wiring. All the load comes directly from the battery. Popping fuses is putting too much current through the system, and increasing the fuse size increases the likelyhood of burning the wires. I highly recommend you go back to the correct size fuse and figure out where your problem lies. (I replaced no fuses on my conversion in my '12, and they are still running strong and working perfectly.)

Who was your supplier? This is definitely a conversion harness issue. Where did you ground out both ballasts? Which headlight connection did you hook into?

I would reverse the charge for your supplier's harness, and order the harness through RaptorRetrofit. Dawson is awesome to work with and provides fantastic service.

THIS, This and more this!

If you had halogen lights, your stock headlight harness is not setup or designed to run Projectors. What you have, or at least should have been, supplied with is an adapter harness. Should have a relay built into it and it will draw power directly from the battery. It hooks up to one of your old headlight's cable only to trigger the relay and tell it to pull power from the battery to power your HIDs.

Both grounds should have been placed preferably behind the radiator mount. If that is not where you want them make sure they are at least grounded well.

Since your lights are working I would assume that your ground is at least mostly working. If you are running off the stock harness than it may be trying to draw too much power to run the light and lift the high beam shroud . Hence why you are having a fuse issue. Only other reason for the issue would be both shrouds being broken, highly unlikely.

EDIT: After some thought another idea may be causing this. If they built the harness wrong it could be trying to power both lights off of the old harness' bulb plug. Instead of only using that as the relay trigger? Maybe, just a thought.

tl:dr, Get a proper adapter harness and install it as per the instructions given. Should fix everything.

Hope this helped

I'm not sure if OEM projectors work the same as aftermarket, but I had a TRS kit do something similar to me once. The way the TRS projector made a high beam was to cycle a solenoid inside the projector which moved a shield inside the projector, changing the beam pattern. That solenoid froze so it would blow the stock headlight high beam fuse. The only thing the stock high beam fuse should do is send power through that solenoid, which has a very little draw. If the OEM projectors are similar, that could be your issue. TRS warrantied mine but you could disassemble the projector and smooth out the solenoid out.

Finally got a response for the supplier and they are sending me a new harness. They figure it's something internal in the harness. Wait and see I guess.

You may need to get a wire relay in between the HID and your headlights, but the HID headlights that I bought from Xtralights just plug and play with no problem at all. Where did you get yours, sounds like a bad product to me...
