XentecUniversal relay wiring harness for all HID single kit H1, H3, H4, H7, H8, H9, H10, H11, H13, 9004, 9005, 9006, 9007, 5202, 880, 884

Hooked it up and it have the loud buzzing the other people said and the left hid would shut off I jumped the relay and it would come on fine the next day in last hope to get it work I reversed the switch plug and everything came on fine I do have a little flicker at idle but I might have to fine a better spot to put the positive battery wire I'll put it right on the battery lead

the harness itself works wonderfully I'm sure it would have been helpful for some people if they were installation instructions included (luckily I already knew what how to install them) but I could see how somebody that does not know could easily get confused. and some of the connectors that go into the ballast weren't the right ones but I was able to make it work. overall yes I would recommend them but only with a precautionary warning.

Easy to install, not a quality part in my opinion from experience with other brands

This harness was a nice simple solution to wiring an hid system in my BMW although I still purchase the warning cancellation modules it all wired up pretty easy and works perfect.

Slow hipping and only worked for a week. My left headlight stopped working so I checked all the connections to make sure they are still firmly connected but my left headlight still won't turn on. I removed this Xentec relay harness and I put back the headlight wiring without the harness and both of my headlights came on. I e-mailed the seller and explained the problem and how I checked all the connections and I asked if I could exchange the harness but I guess he didn't read my whole message because he told me that it can't be the controller that went bad, and asked me to swap my headlight bulb and ballast around see if one of the bulb or ballast is bad. I already said on my initial message to him that both my headlights came on when I removed the relay wiring harness. So instead of a replacement I just asked Amazon for a refund and I will be returning the harness.

Good product easy to install

They respond fast to help me solve my problem. I think for future customers buying these lights they need to made aware they need a wiring harness. It was have solved me a lot of headache and time.

Not to bad

Works great, only complaint is that the ring terminals could have been a little bigger but it was nothing a Dremmel couldn't fix. It was a good length and not too long and the relay itself was big enough to mount with some mounting tape. It was also nice that the fuse was included as well so that's an added bonus.
