Secondary Harness Wire Descriptions
H2/1 GRAY/BLACK (-) Diesel Wait-to-Start Bulb Input
Connect this wire to the wire in the vehicle that sends the signal to turn on the WAIT-TO-START
bulb in the dashboard. In most diesels the wire is negative (ground turns on the bulb) and the
GRAY/BLACK 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 Wait-
To-Start Bulb Wire For Diesels 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
NOTE: 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.)
