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

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!

Very good high quality wiring harness for aftermarket led headlights. Was fighting a no low beam issue with my 95 Tacoma for a long time and finally decided maybe it’s time to replace the harness. Ordered a cheaper one prior to this one and only one of my headlights worked, so I ordered this one put it in and not a single issue. Works great and feels like a high quality kit. I would definitely buy this again and I would recommend it

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.

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.

I have a 1994 Toyota 4X4 standard cab manual shift pickup and a 1996 4X4 Toyota Tacoma manual shift, and wanted to convert both to LED headlights. The wiring on this kit worked perfectly and corrected the dual ground original wiring so the new lights work. (I only needed the kit on the 94'; the 96' didn't require a harness). However, I made two changes. The wiring kit uses a chassis ground; so you find a ground on the fender somewhere and hope your battery to chassis ground is good. Taking no chances I went ahead and ran the ground from both headlights back to the negative battery terminal. (The kits hot wire is already attached to the positive battery terminal). That should eliminate any chance of a glitchy ground in the future. The other thing I did was to seal the connectors and the back of the plugs against water intrusion. The kit has totally open connectors (not potted in any way) and water induced corrosion is just a matter of time. I basically laid out the harness, connected everything, made sure it all worked, and then sealed EVERYTHING up. I dissolved 100% silicone caulk in mineral spirits until a little thinner than syrup. Dipped each connector while still connected and dipped the relays. Hang out to dry, and most of the silicone drips off. Now the harness is "potted"; waterproof. After about 48 hrs good to go. Can still be disconnected if necessary. This kit is just off the shelf parts, but I couldn't buy the parts separately at the price of this kit, and so I'm not bothered that the components weren't sealed already. Small price to pay for keeping things affordable. i suspect sealing it all up on their end would have tripled the price. I have no problem recommending this kit to others.

Nice upgrade to weak headlamps and increased confidence in driving knowing that my small truck can be seen on the road.

Works great on my 61 chevy truck that needed a headlight upgrade this solved the issue of the light turning off intermittently

This is a. Must have if you putting leds on a older Toyota pickup it's definitely a plug and play easy to do

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.
