Wiring (continued)

Violet Wire: (+) Common Door Pin Input

The violet wire connects to the common wire of the vehicle that switches on the dome light. Normally this wire is located at one of the door jamb switches. For some vehicles it may be necessary to connect the violet wire directly to the switched turn on wire at the dome light. The violet wire connects to positive switched circuits only.

Orange Wire: (-) Ground when Armed Output

The orange wire is typically connected to an optional starter disable relay as shown.
