As an owner of a 1995 Toyota Tacoma, I’ve experienced my fair share of electrical issues, particularly with the headlights. Over the years, I noticed my headlights weren’t as bright as they should be, and I was dealing with dim, flickering lights that weren’t just frustrating—they were also unsafe. After a lot of research, I decided to try the H4 Relay Harness Kit for my Tacoma, and it’s made a world of difference.
Why I Chose This Kit
The primary issue I faced with my truck’s headlights was the dreaded dual ground problem that many older vehicles, particularly Toyotas, tend to suffer from. This problem stems from the headlights drawing power directly from the stock wiring, which isn’t built to handle the higher current demand of modern, brighter bulbs. Over time, this can lead to dim lighting, flickering, or even failure of the headlight bulbs.
The H4 Relay Harness Kit is designed to fix this issue by bypassing the stock wiring entirely, providing a direct, stronger power source from the battery to the headlights. I was looking for a solution that would not only improve the lighting but also prevent future electrical problems, and this kit seemed to be exactly what I needed.
First Impressions
When the kit arrived, I was impressed with how well it was packaged. The H6054 7×6 Polycarbonate Headlights were clear and seemed very durable. I was a little intimidated by the wiring aspect since I’m not the most mechanically inclined, but the instructions were straightforward, and I quickly realized I could handle the installation myself.
The H4 relay harness itself is well-built, with high-quality wires and connectors that felt secure and sturdy. The dual ground fix was a major selling point, as it addressed the key issue that had been causing my problems in the first place.
Installation Process
The installation was a bit time-consuming but not overly complicated. After removing my old headlights and stock wiring, I followed the step-by-step instructions to install the relay harness. The most important part was making sure I correctly connected the dual ground wires, which can sometimes be tricky if you’re unfamiliar with automotive electrical systems. I’d recommend taking your time to ensure everything is properly connected.
Once the wiring was complete, I attached the new headlights, which fit my 1995 Tacoma perfectly. The connectors clicked into place with no issues, and the entire process took me about two hours.
The Results
After installation, I couldn’t believe the difference. The lights were significantly brighter, and they stayed steady with no flickering. The true benefit, however, was the reliability. With the relay bypassing the stock wiring and providing direct power from the battery, my headlights now operate with consistent brightness without the strain on the original system.
Driving at night is now a much safer experience. The improvement in visibility is noticeable, and I no longer worry about my headlights failing or dimming during a long drive.
Why This Kit Works
The key to why the H4 Relay Harness Kit is so effective lies in its design. By sending the current directly to the headlights from the battery, it bypasses the weak stock wiring, which often struggles with higher currents. This avoids the common dual ground problem that leads to voltage drops and dim lights in older vehicles.
Additionally, the polycarbonate headlights are tough, resistant to road debris, and maintain their clarity over time. Paired with the relay harness, they deliver a significant upgrade over my old, aging headlights.
Final Thoughts
As someone who’s not an expert in car modifications but loves keeping my truck in good working condition, the H4 Relay Harness Kit was a fantastic choice. It solved a major electrical issue and improved my night driving experience. If you’re dealing with dim or flickering headlights, especially in older Toyotas like mine, this kit will solve your problem.
Rating: 5/5
This kit delivered on every promise, and I’m thrilled with the results. Not only have I solved the dual ground problem, but I’ve also ensured that my headlights will continue to function reliably for the long haul. Highly recommend!

Needed this harness for a 92 Toyota Celica. It was an easy install but for this/my car you have to place the harness and all of its relays/fuses with thought as there is not much room (pop up headlights made it harder). It was also me as I did not want to take off the front bumper to run it under that. I ran it behind/near the radiator. With some careful placement of the wires/relays I was able to get it in place as not to interfere with the headlight when they closed. The issue was not length but more of the fuses/relays getting in the way (for my car). The two big fuses (?) where loose on mines, had to zip tie them so that they will not fall off randomly. Time will tell if the harness will corrode or malfunction, but so far so good.
I did not do a test to see if the LED headlight was brighter with or without the harness (I used an adapter to switch the wires around to get it to work without the harness), so I am not sure if the claim of having this will give you better power for the headlight/H4 style bulbs.

I bought the light kit from these guys too and this was exactly everything you need to hook them up. Plenty of wire to get it through the firewall or run it to a relay (which is what I did). Heavy enough duty to handle light bars or any other high-output lights. I may order a few more of these as I have other spots and light bars I need to hook up.

Vehicle: 1996 Jeep Cherokee Classic
Overview: My headlight switch failed because it provides power to the headlights high/low beams through a factory wiring harness which is underpowered. The factory wiring harness is also the culprit of your dim lights. In my case, the headlight switch burnt up leaving me with no lights.
Solution: I replaced the faulty switch and decided to upgrade to the H4 wiring harness. The H4 harness re-routes power to the headlights from the switch to the battery making the lights much brighter and removing the electrical load from the switch (while the switch no longer powers the headlights it will still function as your headlight switch.)
Installation notes: The H4 wiring harness is truly plug-and-play. The only additional components I used were self-tapping screws, a piece of sandpaper for cleaning up the locations where I terminated my grounds, standard electrical tape, and a few extra cable ties. The overall length of the harness was plenty long for me. There wasn’t a whole lot of extra space to mount the relays next to the battery but it was doable. Had I simply taken 5 minutes to remove the battery it would have been a breeze. Total install time was about 90 minutes.
Results: Noticeably brighter OEM headlights. Happy headlight switch and your vehicle will be ready for H4 aftermarket LED headlights (which you’re going to eventually do anyway right?)
The harness itself comes with an in-line 30-amp breaker for your battery hookup and 2-80 amp relays. As an electrician by trade, I was impressed with the overall product quality. The crimps were strong and secure. The only thing that concerns me about this entire project would be the fact that the relays are not water-proof which may be an issue for the 4×4 crowd who would much prefer driving through a creek than over it.
Final note: There are great install videos on YouTube if you are new to these things. Even for a novice DIY project, trust me, this is as simple and straightforward as the reviews indicate. Last comment, terminate your grounds correctly. Years of experience as a sparky, it’s not the harness that’s not working it’s because you didn’t land your grounds right.

Product arrived exactly as advertised. Installed on 2000 Jeep Cherokee, very easy plug and play design, with install taking about 30min. I cannot say enough about how great this easy upgrade is, making your stock 5×7 headlights waaaaay brighter and offering a plug and play install if you want to upgrade to an LED Lens instead, would definitely recommend!

If you have a vehicle with double ground switching (like my 2000 GMC Safari) and you want LED headlights this is what you need. Easy install and it works.

Pretty straightforward install on my 1994 Toyota pickup. Wiring seems to be of good quality . Be aware when wiring in LED Headlights you will get hyper flashing turn signals. What you need is an EP35 Relay to fix it.
