2- H4 single bulb headlight harness upgrade. $65 each shipped

This is a Plug and Play harness. High beam indicator works on dash. This will work on 40, 55, and 60 series trucks.

I made a few harnesses for me and some other people. I have been running the one harness for several months with H4 55/100 bulbs and it works great. Its plug and play.

Bump for a new week
 
I have some issues with my 1978 40 headlight wiring. They would dim once in a while, now they are out completely, first low beam and now the high beams. I haven't looked into it yet. With this harness what else would I need to have to get my lights back in order? New bulbs? factory switch okay? etc. Thanks.

You would need to have your stock headlight switch and harness working. This harness is for people wanting to upgrade to brighter lights or a higher wattage light bulb.
 
TTT for another week

I am converting my FJ62 headlights to FJ60, just like the look better. Will this harness work? What headlight does it allow me to run?

If you splice into the factory high beam and low beam wire it might work. I dont know any one around me that has a 62 to try it on.
 
Still got two left.
