Installed OEM HIDs and adapter harness, no high beams?

[ljn21]

Hi all, not sure if I didnt do something correctly but I installed a set of OEM HID headlights tonight, gpt everything hooked up, and my highs dont activate? Did I hook something up wrong?? Not sure thats possible as the Morimoto harness seemed pretty straight forward and I am not sure you can even hook it up wrong if you wanted too. Anyone have any idea whats going on?

Strange, mine works fine. What harness did you buy and from what company?

Don't know if I can be of any help since my Raptor is a 2014 that came with HID headlights so I didn't need to do the conversion.

I know on mine there is just a flap inside the headlight housing that moves when the high beams are enabled, not sure if the none HID ones have the same thing. I believe the non-HID Taurus and Fusion models had this.

The only thing I would suggest is check the HIGH beam fuse, I am assuming there is one.
Check the grounds, make sure you don't just use a self tapping screw without removing the paint underneath. Personally I ALWAYS ground to a factory ground point/stud.
Unplug and replug the connectors on the Morimoto harness, I have seen dirty connectors on new harnesses from other products cause weird issues.

I hope this helps

That helps from the perspective from knowing that yes, they are supposed to work.

I purchased the harness as 'new other' from Ebay, the seller said it was a TRS harness, I only paid $50 so I thought I was getting a deal...guess the joke is on me...my stock halogens both low and high work fine so its got to be the harness.

The odds of both sides having bad shields or something like that would be way to high, its got to be the harness. I ordered a new harness and alerted the seller that if I tried the new harness and it proved his was bad, I would be requesting a refund. The new harness should be here mid week.

Thanks for all the info, my stock halogens work fine, since I had trouble, I had to swap the stock halogens back in. Silver lining I guess - I think I can swap headlights in about 10 mins now, lol. Hoping new harness fixes the issue.

The relay on the harness is bad, is it the new water proof connector style harness ? If so you can just swap out the relay from the new harness when it arrives.

Thanks Everyone - new harness arrived on Friday and got it installed, everything is working as it should. Did some experimenting and like Raptor Retrofit mentioned, the relay was bad. The connector that goes to the stock passenger side harness plug was also bad, it was very loose and when it would wiggle around, the lights would cut in and out...ended up swapping the whole harness out, will send the defective one back to the Ebay seller who was understanding about it and will issue full refund. Thanks everyone!

Here is a pic showing them on the truck, look great!

I realize I am a year late here but where did you ground your harness to? I am hoping there is an existing one on either side, don't want to grind off paint and use a self tapper as it invites rust.
