    I recently purchased a used 8ft boss plow for my 98.5 dodge cummins diesel. Upon installation of harness, its doing strange things. My high beams dont work, only the low beams, and at one point when I put my lights on, the pump would start running. I checked all my installation instructions and everything is in the proper place. This plow was installed on a ford superduty f-250 prior to my buying it. the headlight pigtails fit my truck perfectly. I have the smart touch control and preliminary test prove that is ok. Any suggestions would be greatly appreciated. Also I have the undercarriage that fits I believe 97 and newer ford superduty series f250 and350 for sale. Its for the rt3 blade with smarthitch, and am in need of the undercarriage for my 98.5 dodge if any one knows of anyone selling one. thanks for you help

    Dodge Wiring

    When you were installing the harness did you notice the small two pronge vehicle option connector by the relays. check and see how it's pluged in, reverse the connector and see if the lights work properly. Let me know.

    john, thanks for the reply. could you be a little more specific about this two prong connector. Idont recall seeing any, especially around the relays. Its a vehicle option plug? where exactly should i be looking? under to cover where all my relays are located? thanks for the help

    Connector Location

    If you look at the harness in the area around the relays there should be a connector that changes the polarity of the harness to operate on a Dodge. One wire is white and the other one is black if I can remember correctly, you just cross the two. Didn't you get the wiring diagram for the harness? If not you can get it of the Boss web site.

    john, i did download the wireing diagram off the internet. there are two small wires that go to solonoid. one is the solonoid ground and the other is white with a black strip. I wired them up accoding to the schematic, but i was afraid to swap them. ill have to try that and see if thats what you meant. would that change the polarity because the instructions weren specific to my dodge

    Well I'm looking at the page and it shows you a picture and says how to wire them correctly. Trace though the wiring and you'll find it. John......
