    MM2 plow works fine. Only thing is the left headlight on plow will not work. Dodge truck with 4 port module. Is there a jumper I must add to the harness connection to make this work. part number 8436. Changed the right and left bulbs and cannot get left to work.

    My Dodge is a 2500

    Same problem and my high beam indicator also stays on. Will what BNrian describe work on the 2500 or is there a different jumper location setup needed.

    My knowledge ends with that link. I would PM Brian and ask him.

    Never got the PM. What I described in the other thread also applies here other than if the bulbs are HB1 the wire colors are just opposite. Make sure your harnesses are wired correctly for the headlamp type on your truck. Don't assume that both headlamps are the same , as they could be different. The other issue with the left light out, is it just low beam? If so you will need to configure your configuration plug that is located about 18" back from the connector on port #1. There should be a jumper wire coming out of Pin B and gets inserted into Pin A or C depending on whether your truck has a positive or negative common at the headlamps. The easiest way to do this is to take a flathead screwdriver and bridge the center tab to one of the outside tabs - one combination will light up the left headlamp - this test should be done with the lights on. Do not bridge the two outside tabs or you will need a new module. let me know if this helped.
