Reverse Camera Wire Connection
1. You will need to locate the reverse camera harness. If you are installing the NU-GM3 into a Cadillac SRX, Chevrolet Equinox or GMC Terrain,
the reverse camera harness is in the tailgate (Fig A). If you are installing the NU-GM3 into a Buick LaCrosse, the reverse camera harness is in
the trunk lid (Fig- B).
2. Now you will need to locate the reverse camera wire. In the SRX, Equinox & Terrain the reverse camera wire is the lt. green wire in pin 6 of the
16 pin plug (Fig- C). In the LaCrosse the reverse camera wire is the lt. green wire in pin 8 of the 10-pin plug (Fig- D). Please verify that this wire
shows 12v (+) when the vehicle is shifted into reverse.
3. Connect the red camera turn on wire from the NU-GM3 to the lt. green wire using a diode (Fig E). The diode is needed to prevent the reverse
lights from coming on when the reverse camera is activated.
4. V
erify that the reverse lights do not come on when the reverse camera unlock feature is being used.
