    Bought this item and was happy and eager to install it once received. Very simple because it’s plug and play. After installing this item, 2 hours later I went to do an errand and my vehicle was dead. I had to buy a new battery ($260) because it was so dead that I couldn’t jump it! They were definitely very fast at the communication, and wanted to find out what happened, but I wasn’t willing to experiment with a $26 harness to another $260 battery. So I took it as a loss. Definitely bummed!

    Hey there. Sorry, we weren't able to resolve the matter. We do not believe the wiring harness with the relay you've purchased from us was the culprit in the matter, as it doesn't have components that have the capacity to drain a healthy battery in 2 hours. Hope you were able to find what was at fault.

    Works as it should. Happy accident.

    I was looking for a Worthy set of relays to make these led headlights work with my old Suzuki. And I accidentally ran across this while searching. And for the cost it is well worth not spending the time building your own harness and relay. It took 10 seconds to hook up to make sure it worked. And less than 20 minutes to actually install the harness and tie it up out of the way. Wire is kind of small but should be sufficient to carry the load for LED headlights. But the coating on the wire is nice and thick and has nice black wire loom already on the harness. No need to modify any part of this harness. Great product!!!!!!

  • H4 headlight harness

    My dad has a 1994 Toyota pickup which we changed its headlights to led a few years ago. Back then I didn’t knew about this harness and went crazy trying to figure out why the lights didn’t work. Recently I saw a YouTube video about a similar trick with similar headlights and learned about the harness. So I picked up a harness and installed it, boy dose it work well. I wish I knew this back then. In short it works great and the trucks lights work properly.

  • Works perfect with my led headlights on my 95 Toyota Tacoma

    You need this if you're planning on installing led headlights on a Toyota Tacoma because Toyota uses 2 grounds and this converts it to 1 ground. We tried rigging the wires up before buying this and it was a nightmare so I bought this and had the led headlights working perfect within 10 minutes, I'd highly recommend this item and I'd buy another with no hesitation.

  • Suzuki Samari

    Suzuki Samari owner for 30 years. This is a great product! It allows you to install the latest in headlight technology. Super easy installation! You will be amazed at the improvement this makes to your safety and your Samari's electrical system. Not having to power headlights anymore. The relays are all the original system needs to power. This harness connects to the alternator output stud! Orginal Samari wiring was marginal at best. This is a great product to relieve my tired old wiring of powering the headlights. This is a must have!
