Check snow plow lights and blinkers to ensure proper operation. If operat-
ing in reverse (i.e. driver side blinking instead of passenger side), reverse the
harness connections.
Note: All electrical connections should have both ends coated with a dielec-
tric grease (Meyer Part # 15632) prior to nal installation. This will ensure a
good connection and help in preventing corrosion.
