## Questions & Answers

**Q: Will this work on a 1985 four runner?**
A: jeez...every three months the same question...It'll work great if you're intent is to to set your vehicle on fire and collect the insurance...IT'S GARBAGE!! ...the wire is criminally undersized for the application...it should be 14-16g but it's only 22g ...this can cause it to overheat, melt the insulation and start a fire.....

**Q: Did not come with manual, where can I find it online?**
A: Dear customer,

Pretty sorry for this trouble. Kindly please send email to kaslight2@outlook.com, we will send you the manual accordingly

**Q: Will this work on an 87 toyota pickup ?**
A: I installed it on my 88 Toyota pickup 2wd. The high beam did not work. The high beam relay would work but would not turn the high beam on. Found the wiring on load side of the relay was wired wrong so I had to pull the wires out and relocate them. High and low work good now. If the relays work, but won't turn the lights on, the issue is on the load side. Check the wiring on the relays.

**Q: Will this work on a 93 chevy blazer if not what harness would?**
A: I dont know alot about Chevy blazer but work great in my 93 XJ. I dont see why not,

## Customer Reviews

### ⭐⭐⭐⭐⭐ Simple. Effective. Amazing.
*by B***R on September 6, 2020*

Vehicle: 1996 Jeep Cherokee ClassicOverview: 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 4x4 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.

### ⭐⭐⭐⭐⭐ Personal Experience with the H4 Relay Harness Kit: Solving My 1995 Toyota Tacoma’s Headlight Issues
*by A***L on January 9, 2025*

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 KitThe 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 ImpressionsWhen the kit arrived, I was impressed with how well it was packaged. The H6054 7x6 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 ProcessThe 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 ResultsAfter 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 WorksThe 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 ThoughtsAs 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: 5/5This 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!
