    i just installed this 8' hd mm2 on a ford f250 everything went smooth on the install. I cant get the passenger side running light to come on i have checked every connection check voltage ,Resistance every thing it doesn't make since there is only one connection for the running lights. what am i missing here? and yes iv checked and even replaced the bulb. any thoughts would be awesome! im sure its something simple im just not seeing it .(probably because im about sick of working on this truck)!!!:realmad:

    Are you talking the yellow parking/running light or the main headlight?

    And you have the 3 plug at the grill. And a 3 plug Iso module correct?
    Also does your turn signal work on that side?

    Looks like it might be in the headgear wiring. One power turns on both lights

    I don't know what pin it is on the plow side headlight connector, but you can use an ohm meter and test the wires from the bulb socket to the plug checking for continuity. That will for sure tell you it's the harness. Check for any kinked or broken wires from the plug to the light.

    I've had bad connections at the socket before. Check the wires prior to the socket back to the plug to be sure it's not in the socket.
    Good luck.
