6-6 Lighting When the wiring is connected to an auxiliary roof-mounted lamp, pressing the bottom of the button will activate the lamp and illuminate an indicator light at the bottom of this button. Pressing the top of the button will turn off the roof-mounted lamp and indicator. The emergency roof lamp circuit is fused at 30 amps, so the total current draw of the attached lamps should be less than this value. The attachment points for the roof lamp circuits are two blunt cut wires above the overhead console: a dark green with blue stripe switched power wire and a black ground wire. For more information on roof-mounted emergency lamp installation, see the GM Upfitter website at www.gmupfitter.com or contact your dealer. If the vehicle has this button, the vehicle may have the snow plow prep package. See Adding a Snow Plow or Similar Equipment on page 9-105. Interior Lighting Instrument Panel Illumination Control Cargo Lamp This feature controls the brightness of the instrument panel lights and is next to the exterior lamp control. D (Instrument Panel Illumination): Move the thumbwheel up or down to brighten or dim the lights. The cargo lamp provides more light in the cargo area of the vehicle, if needed. The lights inside of the pickup box also turn on, if equipped. Press the switch down to turn the cargo lamp on or off. The shift lever must be in the P (Park) position to operate the cargo lamp.
