Connect this wire to the wire in the vehicle that sends the signal to turn on the WAIT-TO-START bulb in the dash-
board. In most diesels the wire is negative (ground turns on the bulb) and the GRAY/BLACK wire can be directly
connected to the wire in the vehicle. If the vehicle uses a positive wire (12V to turn on the bulb) a relay must
be used to change the polarity. (See Finding the Wires You Need section of this guide.) Here are some common
colors of this wire:
■ Chevrolet and GMC trucks - Light blue or dark blue
■ Ford Trucks - Black/pink
■ Dodge Ram Trucks - Orange/black or black/orange
N NO OTTEE!! A 1-amp diode must be installed in line on the factory wire between the wait-to-start
indicator and the ECM. (See the following diagram for details.)
This wire provides a second unlock output for progressive locks. Refer to document 1041— Door Locking System
Wiring Guide for specific applications.
