Easy way to rewire your headlights

March 02, 2014
I bought this harness to simplify the headlight wiring on my Model A rat rod. It is made to plug into your existing headlight harness and make your lights brighter, but it works great by itself. I am no wiring guru, but I had very little trouble hooking it up and getting the lights working properly. For my install, I used Speedway's 3 position headlight switch. This isn't necessary if you"re using it as an add on....I was starting from scratch - with no existing wiring. The price was right and the quality was pretty good. I will definitely buy more of these for other projects that I have coming up.
Pros:
  • Great price
  • Good Quality
Yes, I recommend this product.

Truely painless

May 04, 2014
This harness could not have been easier to install. Talk about plug and play, to a point that all I needed to supply from my side for a screwdriver, zip ties and a cutter to cut the zip tie excess. Worth the money for not having to build one yourself. My 65 mustang now has halogen headlights.. Brighter than ever before!!!!
Pros:
  • Easy
  • comes with everything
Cons:
  • None
Yes, I recommend this product.

I don't think you need to alter it at all. Neither this not your factory harness will need any altering. It takes signal off your old headlight sockets and uses that to activate the relays which inturm pull power straight from the battery. The harness comes with fused wires that are detachable via a snap on connector. So if a short happens , easy to replace. Instructions that come with are great.

The harness # 910342630 is for cars with two headlights total that have dual filaments for high and low beams. If you are using on a vehicle with 4 headlights the three female plug in will need to be removed and two of the two terminal plug ins installed. The ground will loop from one plug in to the next and the other two terminals will have the two power leads, one for low and one for high beam.

What is the wire gauge of the power leads?
