    When hooking up two of the westerns we have before this latest storm, something weird happened.
    When plugging the harness together which normally automatically turns off the truck lights and turns on the plow lights. That didnt happen, the passenger truck light went out(drivers side stayed on) and no plow lights. The high beams on the plow lights work though. This happened on both trucks
    The trucks are the same make, year, etc The plows are both westerns, but one has the relay system and the other has an isolation module.

    Anyone ever had this happen before? And if so what is the cause?????
