HD headlight harness plug and play - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Tripmiester** · 12-05-2020, 03:20 PM

Looking to upgrade my headlights with the relay style harness that comes from the battery.
Don’t want to buy a cheap one that I will have issues with.
Anyone have good luck with any certain brand?

Thanks
Steve

I used this one. Works well with the Harley Davidson LED headlites. Easy install and LMC is a place everyone has dealt with

Just ordered the harness from LMC. Let you know how it goes. Like the idea of all the power routed from the battery and not the head light switch and high beam switch. Seems to be the two places that are problems with burning up the switch contacts and or wires...may replace the headlights with leds but see how this goes first.

I just built my own. I got like $15.00 in it. Not at all hard to do.
Your going to love it no matter which way you go though.

Did you use 1 relay or 2? What about high beams.

**truckster** · 12-05-2020, 08:34 PM

If you want high beams you need two relays. The wiring is really simple.

**Tripmiester** · 12-05-2020, 09:02 PM

Andy,

Where did you get the parts and do they have ceramic sockets?

Andy4639 · 12-05-2020, 10:00 PM

I used 1 relay for high and 1 for low.

It's a simple job. Run a 12 volt hot from the battery are the alternator to both relays. I bought everything at local parts store.

I used the CE auto electric supply harness.. Thing is way over the top quality..
also put in the JEEP headlights and its bright bright in the shop.. we shall see how she does on the road....

**Tripmiester** · 12-06-2020, 09:12 PM

I’m going with the one from CE electric, do you know which one you ordered the part number by any chance?

**zschary** · 12-06-2020, 10:20 PM

i ordered the h13 but thats because i am running those jeep headlights and it plugs right in to them..

the others i think are the same idea, i had to hook up a couple grounds, a hot wire to the batt post and three wires to the existing headlamp plug coming from the harness.. The relays are sealed high end ones, and the whole harness is covered in non abrasive material and is perfect length.. Everything i get from these guys is great and right on..

For $200.00 I will build you a harness that will work as good as that one. Mine has been working now since 2007. No problems and still running the same relays.

Mine just ant that pretty though. My thread.
