• GND must be connected to the vehicle chassis ground.
Caution: Inspect the cable shield to verify it is connected to chassis
ground. If there is no connection from the cable shield to
chassis ground, one must be added at this time. Use a jumper
wire to connect the cable shield to chassis ground as shown
below for the appropriate type of power supply installed on the
vehicle. A jumper wire, as shown in the illustrations below, may
be present to attach the chassis ground to the white wire of the
power cable. This wire is not necessary but can be left in place
if present. For proper screen blanking, verify the yellow and
green wires are attached to the screen blanking box as shown
in the illustrations below.
For this model, follow the diagram below to attach the power cable shield to
chassis ground:
