    When you plug in the lights to the plow.
    are they suppose to cancel out the head lights to the truck.?

    I went to pick my plow up and the plow lights are not working when plugged in..
    The truck lights are still working though..
    checked connections and all seem to be solid.

    Any help?
    Thanks before hand..

    does it have the old 6 pin hook up or the EIS plugs? If its the old rubber 6 pin connector relay is bad or stuck. If its the EIS idk?

    The plow 28 V with Down Pressure is about 8-9 years old still in great condition though.
    3 point hookup on the plow & the hookups seem to be the 6 pin type..
    I know nothing about Snoways this is my first one.

    Where would the relay be located..?

    Thank you for your help

    With the plow being that age it is not EIS but will have a relay under the hood to switch the lights from truck to plow.

    What year make and model truck do you have the plow on? I can give you some links to wiring diagrams if you let me know. If the relay is original I would suspect that to be the issue.

    Are you sure they are plugged in properly? Every year I see units with pout working lights that turn out to be operator error. Double check to see if you have plugged in to a cover instead of the harness. You should have two separate plugs on the end of two separate wire harnesses. The passenger headlight holds the trigger. if the parking lights on the truck don't work neither will the plow lights. If the passenger light is not plugged in to the passenger side of the harness the plow lights will not work. Make sure the headlights are connected by a white ground wire between them.

    Double check all that and let us know.

    might be able to find them by turning lights on without truck running and plug and unplug the light and listen for the relays to click. My ST would flicker sometimes before I converted it to EIS and usually this would get it work for the rest of the night. I think that the relay box might be by the window washer tank but they could have put it someplace else.

    that is the box the relays are replacable in it, Basher will tell you better than me on how to test the rest of it to make it work. relays are most likely stuck and need replaced, if you hooked it up the way Basher told you to.

    I would check to see that you are getting power to the #2 temminal on the relay when you turn on the parking lights and that all the pins are still in place in the plugs.

    If so replace the relay.

    I have the same plow and every year I clean my connection really good and add that electric spray to the 6 pin connections , so they can be lubed really good and make a good connection for me. My lights did that too and I found out that it was not making a very good connection from the plug in. Just a double check. I would twist mine realy good to make a good connection. These guys on here are really good at the stuff. Keep it up guys. I love this site.
