True Mods H6054 H4 LED Headlight Wiring Harness [Negative Switched Conversion] [Fused] Universal H4 Head Light Relay Harness Kit for 9003 H5054 H6054LL 6014 H6024 6052 6053 Subaru Toyota Jeep Headlamp

This is utterly necessaryI bought LED headlights in housing for my 1996 Tacoma, they were listed as 'PlugnPlay' - They do function but not as both high and low beams just a singular setting with the other being off.This is because the 9004 (my) wiring does not supply a consistent connection to the positive battery terminal - what hibeam light needs in the 9007 replacement. Even though they could be plugged in they were internally wired for a 9007 setup -This harness makes them function as intended with 10 min of work. Literally easy as can be - I went from being sad over my new lights to feeling ecstatic just with this price and use effective harness.For the price point I thought it could be cheap quality - nope it is great. I wish the fuse wire for the positive terminal was a bit longer but this is minor - its worth it

Absolute quality. Very easy to connect. I used this on a 1996 Tacoma that I was adding LED headlights to. This harness was very easy to connect. It worked perfectly with the Tacoma negative applied polarity to the headlights. The LED headlights require a positive applied polarity. The harness was super easy to connect. My son and I got it connected in less that one hour. Quality plugs. Would absolutely recommend.

Works as it should plug and play easy to install

Makes LED headlight usable

I have a 2005 Chevy Astro cargo van, this installed in it perfectly. It did take about an hour and I had to pull the windshield washer reservoir to get to the ground point by the passenger side headlight. But there are ground points on both the driver side and passenger side, no new ground points have to be drilled. I was also able to connect the hot wire directly to the upfitters circuit on the fuse box, the two red wires going to the front that are bolted to studs. I did use a self-tapping screw to attach one of the relays to the front of the vehicle under the hood. This is a very effective way to convert an Astro van with switched grounds into a modern LED headlight vehicle.I paired this with a set of "UNI-SHINE 5x7 led headlight 2pcs 7x6 led headlight H6054 H5054" and it worked out of the box. I did not have to repin or use an adapter to connect them, they just went straight into the plugs provided after wiring the harness. Headlights work as expected, daytime running lights come on as before, daylight sensor works as expected, and obviously high beam low beams work great.

Worked great for adding LED headlights to my 1999 Toyota 4Runner. Very simple install, took less than 10 minutes to do. Would definitely purchase again if needed

So far so good. The wires were a bit short, but I made it work. I put some new Alpharex headlights in and they kept blowing my little 10amp headlight fuse causing me to loose my rear tail lights and my DRL's . Hopefully this will take care of that problem. The wires are pretty thick for the price-14awg. The only other brand I could find that could compare to that was Hella, although Hella does come with 2 fuses rather than just one, like this brand, and it's about the same price. There are other brands out there that use 12awg ,but their running 179 bucks. This is working just fine. I may change it out to the 2 fuse hella, but for now it's working. Oh, and the instructions are actually very good, so if your having a hard time finding a YouTube video on installing these don't worry.

Had to use this on my 2003 gmc safari for LED headlights, they would not change from high to low beam. After this was installed, all works like it should. If you do the rest of the turn and parking lights, you will also need to change the blinker relay for an LED rated one to stop the fast flash of the blinkers. This harness is easy to install.
