Electrical Plug Identification

There are multiple different wiring scenarios that have existed over the years for Western Plows. In an effort to simplify the identification, we’ve taken some photos that show the different plug options to help you identify them. Other areas of our website will reference a “relay system” or “isolation module” system, and this will help you know what you have. If you have other questions please don’t hesitate to contact us.
