Toyota Headlight Relay H4 Harness Kit - 1Set 2 H6054 Wiring for 95-97 Tacoma 88-95 Pickup - Fix Dual Ground Problem

Easy install and good product

Arregló mi problema de solo luces bajas y voltaje ya que brillan más mis luces led y facilita el manejo de noche.

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.

After looking on Jeep forums was recommended this product to upgrade poor lighting. Very happy with product, easy to install, plug and play as advertised, fixed problem as advertised.

My 1992 VW did not come with proper headlight relays. This puts a lot of power through the switch and causes dimming of the headlights. This relay was a relatively easy install and well made product. I did extend the ground from the other side over to the main ground and connected to the battery directly. Installation was pretty straightforward and my headlights are SOOO much brighter now. I'm so glad I did this update to my wiring.
