1967 - 1972 GMC Heavy Duty Headlight Harness
Our Heavy Duty Headlight Harness specifically designed for the 67-72 GMC trucks with dual headlights. Our HD Headlight Harness's are the top of the line, and are constructed with quality materials. They are 100% "Plug n' Play" so there is no need to cut or splice any wires what so ever. They feature 4 HD Ceramic H4 Headlight plugs, to ensure a long life and can handle very high wattage bulbs. The standard high beam bulbs on the GMC's utilized a 2 prong plug from the factory, our harness utilizes a standard 3 prong H4 plug, one pin within the the plug simply doesn't get used on the high beams. The harness will work with any headlight set up that utilizes a H4 style plug (eg. Sealed beam, Halogen, HID). With this harness installed, it will draw your power for your headlights directly from the battery (taking all the load off of your OE Headlight switch) and give your headlight the full 13.8V+ they need to run at 100% and give you a very large upgrade in light output!
------------------------------------------------------------- Below are a few of the benefits of upgrading your headlight Harness:
-------------------------------------------------------------------------- Regular Price: $99.95 Shipping: $9.95 via USPS Prioirity Mail to the lower 48 States ONLY Shipping to Canada: $15.99 via USPS Payment: PayPal or a US Postal Money Order To Order: Simply send us a PM with your PayPal address and we'll send you an invoice with a total via PayPal Part Number: 6772GMCHD312 ------------------------------------------------------------------------ Thanks for looking and have a great day!

Re: 1967 - 1972 GMC Heavy Duty Headlight Harness
I have almost 3000 miles on the truck and my LMC harness is working flawless after I Color matched the wires to the stock plug. I still do not know what I did differently than everyone else?

Re: 1967 - 1972 GMC Heavy Duty Headlight Harness
The harnesses from LMC come wired incorrectly and does not work. Thats what he is talking about. Looks like this harness here is the one to get.

Re: 1967 - 1972 GMC Heavy Duty Headlight Harness
Alright you got me. Been staring at this for over a week now. I won't need it for a couple of months and was going to wait. I would also like a set of ground straps and a power door lock kit with extra remote. Thank you.

Re: 1967 - 1972 GMC Heavy Duty Headlight Harness
I'm vouching for this harness- I originally bought an LMC harness and after sending the first one back- and getting a second one that also was wired incorrectly I gave up and have been MORE than satisfied with this plug and play harness-- great product!!

Re: 1967 - 1972 GMC Heavy Duty Headlight Harness
What width are those spades that plug into the factory lamp socket to activate the relays? I could never find any wider than 0.250".

Re: 1967 - 1972 GMC Heavy Duty Headlight Harness
The connectors that we utilize to connect the OEM headlight harness to our HD harness are specifically designed connectors for this purpose. The harness's do not use a standard readily available spade connector that you find at your local parts house.

Re: 1967 - 1972 GMC Heavy Duty Headlight Harness
They don't suck, they just need to have some wires switched around to make them work properly. I have the LMC harness and after I swapped the wires it works fine. I forget the exact swap, but I'll see if I can dig up the info.
