Electrical Connections
Notice: Before modifying or adding any wiring,
be sure that it will work properly with your
vehicle's wiring system. Because there are so
many modifications that can be made for many
different bodies and accessories, GM cannot take
responsibility for any changes made. Such changes
may not be covered by your GM Warranty. Have the
work done by an experienced electrical technician.
All wiring must be properly protected by fuses, etc.
and must be routed properly so that it will not be
cut, pinched or rubbed by other parts of the vehicle.
Do not route wiring in areas where it will be very
hot. Be sure not to overload the vehicle's wiring,
connectors and components. All added wire must
be at least the same size as the wire being attached
to for proper fuse protection.
Installation Instructions 12Volt
Accessory Power Supply
1. Disconnect the negative () battery cable at the
battery. The negative () battery cable must be
disconnected before the positive wiring lead is
connected to the power accessory.
2. Locate the power supply harnesses, one under the
instrument panel near the center of the vehicle,
and one within the driver side rear cargo area jack
stowage compartment.
3. Prepare the wires that are to be used to connect
the power accessory. Do not remove the unused
wires. Tape unused wires back in their original
position under the instrument panel.
4. Complete the wiring installation of the customer
added accessory with additional wire required for
the specific electrical accessory power connection.
The wire gauge, 12 gauge (3.0 mm²), should be
the same as the wiring of the installed harness.
5. The ignition must be turned to OFF prior to
attaching the cables to the battery, or serious
damage to the Body Control Module (BCM) may
result.
The windshield wiper switch and the radio must be
turned off before attaching cables to the battery.
