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.

I bought this item because the company from which I bought my HID kit was out of stock on a relay harness. It's probably not as robust as theirs, but it's also $15 cheaper!As others have said, I had to crimp on a bigger terminal for the power source - no big deal.Also, other reviewers have mentioned that the relay supplied with this harness is not of the best quality and they suggested upgrading it. Happily, I took their advice and went to Advanced Auto and bought another 40 amp relay to have with me in case of emergency. On only my third night using this harness the relay failed! Popped in that "emergency backup unit" and was back in business. (Am going to have another one with me at all times just in case.)So this harness is not without its flaws, but over all it does get the job done. Good value at the price.

This is a quality relay setup at a valuable price, I have two hid/relay systems lo/hi on my vehicle...seems all the negative reviews I can imagine are from installation errors or lack of electrical/relay knowledge.... I will say the ring terminals and fuse assembly are a little on the flimsy side, I would recommend replacing them with weather tight connections...using dielectric paste on connectors and having clean and tight grounds are very important. Have not had any issues with this harness or both of my innovated premium kits, works every single time without a doubt.

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.
