LMC HD headlight harness relay kit help!!
so I have a LMC HD headlight relay harness kit and it has a three prong plug in and our trucks have only two wires a tan wire and a green wire! has anyone wired one up to work with our trucks?? in the LMC harness each light has a yellow wire and a blue wire going to it, they then go to two relays one for low beams and one for high beams, both yellow wires go to one relay and both blue wires go to the other! there's a blue wire with white stripe that join both relays a white wire comes off one relay and a brown wire off the other then the brown, white and blue wire with white stripe go to a three prong connector to plug into the trucks harness and I can't figure out what wire goes where!
my thinking is the blue wire with white stripe is a ground and the white and brown wire would plug into the trucks harness, just not sure any help would be great I figured I would ask here cause this is a 66 truck i'm adding the harness too, thanks guys

Re: LMC HD headlight harness relay kit help!!
the three prong plug i'm talking about is not the ones that go on the bulbs themselves it's the three wire prong they want you to connected into the factory two prong green and tan wire going thru the radiator support on the driver side!

Chad,
If you have a picture of the relay and the wiring harness I could probably help you figure it out. B |
