auxiliary harness (H2) wire connection guide
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 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 indi-
cator and the ECM. (See the following diagram for details.)
H2/1 GRAY/BLACK (-) diesel wait-to-start bulb input
PINK/WHITE (+) output to second ignition circuit
PURPLE (+) starter output
ORANGE (+) accessory output
