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 — 12-Volt

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 harness under the

instrument panel near the passenger’s side of the

vehicle. The wire bundle consists of the pink

ignition (IGN), orange battery (BAT) and black

negative (NEG) wire feeds.

3. Remove the tape to release the wire bundles from

the power supply harness.

4. Remove the 40 amp MegaFuse that is taped to the

wire bundle. Set aside for installation, after

equipment wiring is complete.

5. 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.

6. 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 mm), should be

the same as the wiring of the installed harness.
