If using a pac gmrvd2 and your vehicle has 2 overhead video screens you must make the following connection.

Pin 8 – Lt. Green – Screen 2 Video +

Pin 10 – GREEN/ Black – Screen 1 Video +

Pin 18 – White – Screen 2 Video -

Pin 20 – WHITE/ Black – Screen 1 Video -



These are all found in the Black 20Pin connector that the GMRVD2 plugs into.

You must connect screen 2 wires to screen 1 wires to get the rear monitor to work.

Thank You for not archiving this one. I needed it again and knew I would have posted it when I got the info from PAC.
