About this item

  • YOUR VEHICLE NEEDS THIS - Swapping out old headlights ( H6054 H5054 H6054LL 6014 6052 6053) for LEDs on negative switched vehicles like Toyota, Subaru, Mitsubishi, or Suzuki, is not a simple job. But with our plug-n-play conversion harness it can be!
  • CONVERSION MADE EASY - Save time, money, and headache by utilizing this wiring harness to convert a ground switched headlight system (2 toggled grounds + 1 constant hot) to a positive switched headlight system (2 toggled hots + 1 constant ground).
  • NO LOW-QUALITY PARTS HERE - Designed with two durable relays, high-temperature ceramic headlight sockets, and heat-resistant polycarbonate wire loom. This harness is built to last.
  • THE WAY IT SHOULD BE - We set out to build a harness that would install with as little effort as possible. The result? A conversion harness that takes only minutes to install and works every time.
  • PRESERVE YOUR STOCK COMPONENTS - The beauty of this conversion harness is that you don't need to cut into your stock wiring harness. This dramatically reduces the install time, and if you need to, even makes the process completely reversible.

Product Description

H4 Headlight Conversion Wiring Harness
H4 Headlight Conversion Wiring Harness

Wouldn’t it be nice if every LED headlight upgrade was plug-n-play simple? Yeah, we thought so too. If your ride uses an entirely different type of headlight circuit, then this is for you. Save yourself money, time and headaches and buy our conversion harness for a plug-n-play experience.

H4 Headlight Conversion Wiring Harness

When designing our conversion harness, we made sure that it was something we’d put in our own cars. Built with two heavy-duty Bosch style relays, high-temperature ceramic sockets, heat resistant polycarbonate wire loom and a 30 amp fuse, this conversion harness is engineered for durability.

Was fairly easy to install and seemed to be a good quality harness. My new LED’s are amazing and I could not have done it myself without this terrific part. I had to remove several things from the inner fenders to tuck everything away nicely before putting them back but it was worth the effort. I had to remove the air cleaner box, the headlight washer reservoir and the power steering reservoir so I could mock it all up and see if it was gonna fit where I needed it to. Had to loosen the 4 radiator mounting bolts so I could slide the harness along the top radiator support and tuck it all in nicely and zip tie so it looks factory.

Reviewed in the United States on February 24, 2019
Verified PurchaseEarly Reviewer Rewards(What's this?)
The instructions were straight forward. The instructions though were written as if I was installing new LED headlights at the same time. I was not. I was wanting to reroute the factory headlight power from the switch on the steering column and through the new harness straight to the headlights.
This would allow more voltage to the lights and should result in brighter headlights. This would also reroute power from routing through the headlight switch and avoid the common "burning out" of the headlight switch.

I tested my voltage from the factory headlight connector and found it 12.5 volts without the vehicle running. I was a bit surprised that after installing the new harness that my voltage did drop to 12.2. But I suppose this could be from having it sit with the parking and tail lights on drawing down the battery some.

After I installed the harness and started the vehicle the voltage to my headlights was 14.4 while the engine was running. I did forget to test the factory harness while it was running for a comparison.

I will say though after installing the harness and driving in the dark the lights DID appear slightly brighter, not the 50% brighter that I saw another reviewer claim, but brighter. Maybe if I upgrade (is it?) to LED headlights it will be even more?

Even if there was no increase in the headlight brightness I am happy to have a more reliable harness installed that has a fuse and two resisters in the harness and getting all that voltage away from running through my factory headlight switch.

5.0 out of 5 stars This is the plug in solution for your toyota
Reviewed in the United States on May 10, 2022
Verified Purchase
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.

Compré este arnés por que instalé unos faros LED en mi xj, pero notaba que había parpadeo en ambos faros y dentro de la cabina se escuchaban pequeños sonidos de interferencia al encender los direccionales, al instalar este arnés, no solo solucionó los problemas anteriormente mencionados, si no que noté una gran diferencia en la iluminación, pensaba que los nuevos faros LED no podrían dar más, pero esto los hizo funcionar como verdaderamente deben ser.

Recomiendo este arnés en sus XJ dado que el cableado de fabrica con el que cuentan con los años se deteriora y no entregan el correcto voltaje a los faros.
