    Hey guys I have a minute mount 1, the passenger light was broken so I bought a new set. The set I bought only has 4 wires where the old one had 5. I tried to wire the passenger side in but ran into some problems so I it off. With no light on the passenger side the drivers side will not work. Is this normal? Not sure what I need to do to make this work

    You sure you didn't blow a fuse? Did you look at fishers website for the wiring diag?

    Do they have a diag for this? The old lights worked fine the mounting bracket was just rusted out. I figured I would just connect the four wires and leave the fifth hanging. The lights I bought were grounded inside the lense instead of using the black wire with the orange stripe. I'm pretty sure it's some sort of grounding issue because when I hold the wiring harness all of the lights start to blink. If I unplug the harness the truck lights function normally.

    They look identical but the lights I bought have four wires coming out of the light cover as opposed to the five that my old lights had. It's because these lights are grounded within the lense instead of running a dedicated ground line. The lights I bought were for an old plow before minute mounts.

    See if you can get a pic. There should be 5 wires. 2 for parking. 2 for turn. 1 for low beam. 1 for high beam and 1 gnd odd that there's only 4 on an older factory light

    Right, I opened it up and both the headlamp and turn signals are grounded inside the light. So I figured if I just let the black with orange stripe wire hang it would be okay but apparently not. I'm thinking that I will just have to re wire the grounds so that they tie into the orange/black wire.

    I only have a cellphone so getting a pic is out, sorry

    You need to connect the black wire with the orange tracer to the light bracket. Without that wire you don't have a good ground back to the battery.
