MetHoD of oPeRatIon
Headlights
The SnowDogg relay isolation module diverts switched power or ground for the plow high and low beams from the truck
harness to the snowplow lights when the plow is connected. There is no additional draw from the plow lights. The plow
headlights common uses the vehicle headlight harness common (+12V or ground) which is supplied through the light gray
wire. When the plow is disconnected power flows through the relay common to normally closed contacts to the truck headlights.
