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

Finally!! After a year of struggling TRYING to get my headlights to work properly, I found this little device and my problems are solved.. Ive tried HID projectors, wouldn't work, couldn't figure out why... Bought a set of $900 LED aftermarket assembly, didn't work because it conflicted with my DRLs... Stumbled across this a couple of days ago while researching why my LEDs didn't work, figured I could "waste" a little extra money... Just had to put my old assemblys back in, hook up my Innovited HID conversion kit and added this relay and FINALLY my headlights work.. No light fluttering.. No not getting enough power.. No more thinking bulbs were blown, so buying new kits to put in.. This is definitely something you should add if you buy one of their HID conversion kits.. I'm by no means a mechanic but I'm old enough to understand how things work.. Electrical systems I usually pay someone else to do but I got tired of spending money or getting huge quotes for "maybes".. This solved everything, THANK YOU!!

Exactly as described, works great

In the world of high-intensity lighting, where a single failed connection can leave you stranded like a ship dead in the water, the Innovited Universal Relay Wiring Harness steps in like a seasoned first mate. Its construction feels deliberate and rugged, the kind of gear you’d trust on an overland rig heading into uncharted territory. Installation was mostly straightforward—clearly designed by someone who understands that adventure rarely waits for perfect conditions. The harness delivers steady, reliable power to HID setups, eliminating the flicker and inconsistency that plague lesser equipment. My only gripe—and the reason it earns four rather than five stars—is that the instructions could use a touch more clarity, especially for newer deckhands unfamiliar with wiring diagrams. Still, once connected, the system performs like a loyal engine room: quiet, consistent, and ready for whatever darkness waits ahead.

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.

Easy to install , used it on a 2013 civic si with retrofits . Gtr bulbs and hylux balast so far so good 👍

Must have a bad relay because it will only keep the lights on for a few minutes and then they turn off. I can turn them back on, but then they stay on for a few minutes. And then turb back off

Heavy duty

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.

It's a 2 pin even though ad says suitable for 9007 which is a 3 pin
