vinny933 Posted August 24, 2021 Share Posted August 24, 2021 R3 relay lights where blinking wipers going when I turned key on, pulled this relay under hood and it stopped everything works. Is this relay for a wire to the back of the truck for a trailer hookup it's a 2019 granite triaxle dump no trailer plug in the back Quote Link to comment Share on other sites More sharing options...
