XtremeVision H1/H3/H7 HID Wiring Relay Harness, 12V 40A 35W/55W, Compatible with HID Conversion Kits, Easy Plug-and-Play Installation, 2 Year Warranty

TLDR: worked for my 18’ challengerHere’s my long journey of having RGB headlight rings.I purchased the Vland RGB headlights to add some flare to my challenger.Once I got the headlights, I realized I’d would obviously need aftermarket HID bulbs.So I essentially had to drive around during the day because I didn’t have headlight bulbs.Once they finally came, I installed them and it was going good for awhile.About 2 weeks ago, my headlight bulbs started to flicker off and on and sometimes stop working mid drive(extremely dangerous while on the highway).So I did some research and bought this relay so the power would come directly from the battery.Now it works beautifully and just like any other DIYer, it feels like a breath of fresh air after fixing a problem. I will throw in a tip for other challenger owners….I cut a small piece off the positive end so it could fit around the bolt(left side of engine bay when looking from the front). Good luck and drive safe mopar owners.

Easy to set up, works very well with hid conversions

I have a 2012 Dodge Challenger with after-market HID lights installed. After some time I ran into an issue where my passenger side headlight would go out on me randomly and then pop back on later. The issue got progressively worse until eventually both lights stopped functioning. I had installed a brand new HID kit, so I knew it wasn't the bulbs nor the ballasts. Then my next thought was it could be a burned-out headlight switch, so I replaced that as well. I even checked all of my fuses, both under the hood and trunk. Still no change. I began searching online and noticed this was a very common issue. People were getting the lights replaced multiple times to no avail. People were swapping out their PCM's or replacing their TIPM's and all sorts of madness that was costing hundreds of dollars. I'm a dyi gal and refuse to pay the dealer anything because they are a bunch of crooks. I took it to the dealership to see what they thought and no joke the guy quoted me 1k to fix this issue. After I politely told him to kick rocks, I went back to the drawing board. I went back to the original source which was my HID lighting kit and just started over. I re-examined all of wires in the kit and they were flawless. However, once I got to the relay harness (which was original stock that had never been replaced), I was like this sucker needs to be replaced. I couldn't find a MOPAR match. I went to NAPA auto and they were referring to it as pigtail harness, but I knew this one looked different so I started searching on after market sites like rock auto and amazon. I found this one and as I was installing it, I knew instantly that this was the source of my issue. Installation was very easy. Only installation issue I had was the connector of this harness to the ballast didn't quite fit but with a little electrical tape, I made it work. I turned my lights on and voila. Issue resolved. It's been close to a year now. So for all those Dodge Challenger folks with lighting issues where either one or both of your lights don't come on, you may need to check to ensure this relay harness isn't burnt out. The dealer tried to quote me 1K to replace my TIPM and I fixed it for $11.99 with this simple harness. Took me only 45mins. I've been meaning to go back up there and slap him.

I bought this because after converting my charger from factory halogens to factory HID. I was getting flickering. No programming was available to get the computer to recognize a hid system installed so had to use these and they work great.My only complaints are both the power and ground cables could stand to be another 6 inches longer. Very easy to install.I also suggest you double check your cars electrical system first though with a volt meter. My car the positive and negative were opposite of the relay kit. At that point you can either plug the cables in backwards or if you know how you can pop the pins out of the relay harness connectors and reverse them so the cable locks match up again.

While the product seems to work fine I had to extend the wires for the second side at least four feet to reach across my 2015 full-size GMC 1500. Considering the battery is mounted in the passenger side near the firewall, locating this close enough to connect to the battery does not leave enough length to properly route the wires to the other side. While the cost of this harness is reasonable, I don't think adding four more feet of wire to one side would change the cost that much.

I have a 9007 HID setup already but the Hi-Low relay had crapped out. Bought this kit to replace it as it looked identical. The relay is pinned different so if you're looking to swap just the relay think again. Installed the whole harness and realized the high and low beams were working in reversed operation. Swapped the two pins on the connector that takes the factory headlamp connector and it was correct then. Not sure if I got a fluke harness or if they are all like that but if you have that issue swap the blue and red wires on the blue 9007 female connector and you'll be good.

Got a 2015 ram 1500 had to extend the POS and neg wires. Also didn't come with brackets to mount the relay or fuse

Most know Chevy and GMC brand has poor wiring, at lease not enough voltage to upgrade to HID. But this wiring harness did the trick, with the 55 watt ballast it stepped up the voltage straight from the battery. No flickering, no error codes. Nice!
