True Mods H6054 H4 LED Headlight Wiring Harness [Negative Switched Conversion] [Fused] Universal H4 Head Light Relay Harness Kit for 9003 H6024 5x7 7x6 4x6 Subaru Toyota Jeep Sealed Beam Headlamp

So first off, I read alot of negative reviews on this wire harness and was skeptical to buy it, let me just say I'm glad I did. So the white insulator inside the h4 plugs that people complained about being loose is not a problem, it is how the plug is assembled and once plugged in it has no where to go and is tight and secure, and for people complaining about the wires being too small ? Well mine has 12g wire throughout and 10g wire for the main power and ground, which is way more than enough gerth to run 2 led headlights which is what this harness is designed for. And I've also read people complaining about the blue high beam indicator on their dash cluster not working after installing led headlight bulbs? Well mine did work and quit after installing the led headlights also, the led headlight bulbs do not draw enough amps to trigger the factory relay (this harness made it work again), Last of all everything looks and feels and performs and is high quality on this harness, wires, loom, relays and all plugs are solid 👌 . The only thing I changed is the 2 ends that you ground at each headlight harness, I cut off the c loop connector and crimped/shrink tubed on a o loop connector, not necessary but for me I like the loop connectors better to go on a ground bolt vs. The c loop connector. All in all I rate this kit A+++ and ordering another one for my other toyota for doing led headlight conversion.

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.

Definately plug & play. I've wanted to do this conversion for years. AMC did many great things in building the Jeep, but the lectrical system & using the body & frame for ground was not one of them. This harness worked great for a bench test. Then not after I installed it. After more than an hour of testing EVERYTHING, I realized that the ground wire from the old headlight socket still needed to be grounded. Once done, we had lights. Thanks for this si.ple, but effective upgrade.

Easy to install. Instructions were easy to follow

Great product! Installed with Uni-Shine 7" LED headlights. Only issue was that on 87' Suzuki Samurai the headlights are designed with a control and slave lamp design, the control lamp can be on either side. Mine was on the driver's side and the positive wire was too short to reach the battery on the passenger side, easy fix. Harness installs easy and blends in well with original wiring harness.

Worked great on my 94 xj cherokee. Ran the wiring alongside the coolant reservoir hose, grounds to one bolt on each side of the upper radiator support and mounted the relays on the inner fender by the battery. I had more than enough slack

AWESOME MUST HAVE.. MAKE JOB EASY AND CORRECT JUST MAKE SURE TO INSTALL RELAY TO KEEP AWAY FROM MOTOR HEAT ETC..VERY GOOD KIT..

A must have for older rigs converting to LED lights. This is a super affordable way to take the load off of your factory switch and get a dedicated 12v to your headlights. Converted my 1990 Chevy 3500 to LED and I tested with and without. First test, no harness: when the blinkers were on the headlight would flash quickly and they seemed slightly dim. Second test, WITH harness: full brightness, no flashing with turn signals, super clear. Such a simple solution!

Muy buen arnés Fácil de instalar mis luces funcionan muy bien hasta ahora Buena calidad 👌

Plug & play mod for H4 headlights, it has increased brightness and flash response time by a big margin. It's a one-time investment to tune up poor headlights. Make sure you place the relays in a good place away from direct heat.

取り付けも簡単で今のところ問題なく点灯しています。

The connectors and wiring are good quality, and the wiring diagram was easy to understand. Hooked it up, and worked immediately for converting my 1991 Toyota MR2 to LED lights. Thank you.
