Information Center (DIC). To turn the chime

Auxiliary Roof-Mounted Lamp

If equipped, this button includes wiring
provisions for a dealer or a qualified service
center to install an auxiliary roof lamp.
This button is on the overhead console.
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.

lamp installation, see www.gmupfitter.com
