Looking to install reverse beepers on our fleet of cars and trucks also vans does chevrolet use multi plexing wiring to reverse lights or do i need to install a relay? Pick ups S10-3500 series and vans all range from 1999-2008


No need for a relay. Just Ground it to the frame and connect your positive to the power supply wire on the back up light bulbs ( you can connect in the wire harness ). No multi plexing to the reverse lights.
