MN 1973-1987 Chevy & GMC Heavy Duty Headlight Relay Harness's - The 1947 - Present Chevrolet & GMC Truck Message Board Network

VH Coachworks · 04-04-2012, 01:43 PM

Introducing our brand new Heavy Duty Headlight Harness specifically designed for the 73-87 Chevrolet & GMC trucks with SINGLE 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 HD Ceramic H4 Headlight plugs, to ensure a long life and can handle very high wattage bulbs. The harness will work with any single 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!

Yes! We are currently developing the Heavy Duty Headlight harness for the squarebodys with dual headlamps! There will be a pre-sale thread up within the next week, if you would like I can add you to the list of people to be notified when the harness is released!

SBTork · 04-07-2012, 04:29 PM

Yes, please do add me to that list. Thanks!

bigblock73 · 04-07-2012, 06:57 PM

I'd also like to get on the list for the dual headlight harness

**Dieselwrencher** · 04-09-2012, 06:48 PM

I'd also like to get on the dual head light harness as long as it is will work with the 88-91 head lamps. I'm guessing it will, but figured I'd ask.

Hi,
I send you a PM shortly with more details.
Thanks

wklink · 04-10-2012, 04:05 PM

Installed mine today. No issues what so ever, done in about an hour. to be honest, the HD headlights I think cost more than the harness. Look into it if you want better headlights on your truck.

wklink · 04-12-2012, 04:23 AM

Actually might be interested in buying a couple more kits to drop in (get this) a 1965 Fairlane and a 1962 Thunderbird. Both have dual headlight setups. The headlight switches on these cars struggle with higher capacity headlights. I can't imagine that the system would be any different functionally for a Ford vs. a Chevy. If they work I might just get you some business from some of the Fairlane and T-bird owners as well as the guys here. More $$$ for you.

I have a GMC 35 Sierra Classic 1 Ton Dually. Is this a true *plug & play* or do wired have to be spliced? Thanks.

Larry

Hi Larry,

Yes, this harness is a TRUE 100% Plug n' Play! You do not need to cut or splice any wire what so ever! You simply plug your passenger side OEM headlight connector into the new female H4 headlight connector on the new HD Headlight Harness.

Then you simply plug the new ceramic H4 headlight connectors onto your head lights, then bolt the 2 new power wire 3/8" ring terminals to your positive battery terminal, and ground the two #10 eyelets on the immediate left and right of the relay bank.

And your done! Installation is very straight forward on all of our harness's and allows for the cleanest and easiest installation possible!

Oilbrnr · 02-15-2013, 11:26 PM

Don't suppose these will work if the battery has been moved to the DS during an engine swap, correct?

Hi Don. Yes, this harness will still work even if you have the battery relocated to the driver side of the engine compartment. If you have any other questions, please feel free to ask!

bluex · 04-15-2013, 07:09 PM

Can these be made with the 9008 ends at the bulbs to accommodate the Jeep light swap/conversion an avoid splicing into these super nice harnesses? It would also save us from having to buy the expensive pigtails through mopar....
