Universal Relay Wiring Harness for All HID H1, H3, H4, H7, H8, H9, H10, H11, H13, 9004, 9005, 9006, 9007, 5202, 880, 884

I have bought several relay harnesses over the years for various projects, and the quality of them is kind of hit or miss. This harness however is a pretty high quality piece, the wiring is of appropriate thickness, connectors are decent, relay looks pretty good and functions perfect, and the fuse holder seems reasonably secure and weather resistant. This harness was actually purchased for its intended use, for use with a set of HIDs, and it functions flawlessly at that. Very easy to install, simply hook up your power and ground wires to the battery (or other source of power and ground, I chose to use the fuse box and a fender ground for a cleaner install), connect the trigger connector into the car's original headlight connector, and plug the ballasts into the remaining 2 connectors, and you are done.My only complaint with this harness is that the wires that go to the headlight on the opposite side of the car from the battery are too short once you route them nicely out of the way. This harness went into a Hyundai Elantra, not that large of a car, and it was still about a foot too short. I've come to expect this however, and have spare 9006 connectors on hand to make an extension for these harnesses. I did not deduct a star for it because this is an issue with a lot of the harnesses I've bought, not just this one, and this one is very nice otherwise.

Installed on a 2012 Dodge Avenger had to use the relay harness in addition to the installation also purchased the anti flickering capacitors it is still unclear yet whether or not I need them at first without the relay once the engine on started turning off and on by themselves the relay seemed to fix the problem. Now the lights turn off individually if any source of electrical is activated in the car such as the horn or defroster. A simple flick on and off of the headlight switch seems to resolve the situation. Will install the capacitors and see if it fixes the issue. All in all the lights were a good deal for me since I'm on a budget... I had no issue with different color bulbs as did many of the review I read. The connectors are not the greatest quality although I had no problems with them and had to disconnect and reconnect multiple times due to reverse polarity on the 9006 plugs. I would definitely recommend these since they are bright in fact even though the lights are pointed down I still get flashed by oncoming traffic occasionally. Will update later once the capacitors are installed.

The harness was really simple to install, however the relay died within a couple of days having it installed. Swapped for a different relay so hopefully it was just a quality thing and not something with the harness itself.

as described. comes with instruction diagram. wish is came with few tie wraps. otherwise ive tested on my new conversion kit lighting and it works no problem

2015 Sonata Hybrid, after 5 months of having issues with driver's side not turning on most of the times, specially in cold weather I finally found this, I had replaced the ballast 3 times and bulb who knows how many times.This solved my issues, I can't believe this isn't a more common knowledge, so many threads on the internet about lights not turning on.At first it did not work, I hooked up the red wire to positive and black to negative, and lights would not turn on but I could hear the relay clicking.After 45 mins I placed the ground directly to the chassis and that was my bingo moment. Now my lights work 100% of the time!!Great product.

1st, this is not universal by any stretch or for "H1, H3, H4, H7, H8, H9, H10, H11, H13, 9004, 9005, 9006, 9007, 5202, 880, 884" as advertised. The harness comes with 9006 connectors and that is all it fits. I have no idea why they advertise it this way. VERY MISLEADING! The harness itself seems fairly well built, but the leads are pretty short. Unless you have a very straight path across the front of your car and a small car it probably won't be long enough. Another small but hugely annoying fact is that the relay does not come with the mounting tab (something almost impossible to purchase separately) so there is no way to mount it. I should have just returned it. It is just a waste of money collecting dust in the garage.

This was my first experience using HIDs, I'm a bit ticked off because 1. The HID light manufacturer did not specify that this kit was recommended and 2. This kit was 15" too short...so I had to remove the ballast from the PERFECT spot, then extend the power and ground wires.Otherwise it was inexpensive, easy to install and works.Beware, if you have a smaller vehicle you'll be all right, but for a mid sized to larger vehicle, you'll definitely have some issues.

Had flickering and shut off from new hid kit while engine running. Apparently there is AC at the headlights. This kit makes them work perfectly. There just enough wire to get by.
