APPENDIX A
Wire the backup camera directly to your vehicle navigation wiring harness.
The simplest and most robust option for interfacing your navigation is with a lockpick. You can choose
from either a GMX-560 or GEN6 version, depending on your budget and needs. The lockpick will not
only allow you to interface your camera easily, but it will override all the features of your navigation that
are locked while in motion.
The least expensive option is to purchase the CS-GMVSS1 or VSS2 interface harness to connect the
camera directly to your navigation system. For the VSS2 you will simply plug the brown connector into
your radio and connect the camera RCA wire to the VSS connector.
For the VSS1 connector you will need to insert 2 pins into your existing brown plug on the back of your
radio. To install, remove your radio to gain access to the wiring harness. Find the brown connector on
the back of your NAV radio and connect the leads as shown in the image below. There is a red plastic
lock pin that goes through the center of the connector that will have to be pulled out before you can
slide new pins into the brown connector. Wire the red video (+) RCA wire to pin 6 and the black video
(–) wire to pin 7 in your harness. The pin locations are numbered on the back of the plug so just
remember that pin 8 is directly above pin 16, or just make sure you wire it as shown below:
If you already have wires in these locations you can simply use a tap splice to tap into the existing
wires.
