H6/12 WHITE/GREEN WIRE—(-)Diesel Wait To Start Input
(See Start Feature D-1 Programming)
In diesel vehicles it is necessary to interface with the wire that on the WAIT-TO-START
light in the dashboard. This wire illuminates the bulb until the vehicle's glow plugs are
properly heated. When the light goes out the vehicle can be started. This wire is always
at the connector leading to the bulb in the dashboard. It can also be found at the Engine
Control Module (ECM) in many vehicles.
To test and determine the polarity of this wire:
1. Set your multi-meter to DCV or DC voltage (12V or 20V is fine).
2. Attach the (+)probe of the meter to(+)12V.
3. Probe the wire that you suspect leads to the bulb with the(-)probe of the meter.
4. Turn the ignition switch to the ON position.
5. If the meter indicates 12 volts until the light goes out you have isolated the connect
wire and the wire's polarity is negative (ground while the bulb is on).
6. If the meter reads zero volts until the light goes out and then reads 12 volts, you have
isolated the connect wire and the wire's polarity is positive.
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 this wire can be directly connected to the wire in the vehicle If the vehicles
use a positive wire (12V to turn the bulb) a relay must be used to change the polarity.
H6/13 YELLOW WIRE—(-)200mA Ignition 3 Output
This wire provides a 200mA (-) ground output that becomes active after the remote start
sucess, and remains grounded while running.
Ignition 3 output
Some newer vehicles use a third
ignition wire which is required to start
and keep the vehicle's engine running.
If this is the case, wire an IGN 3 relay
(not supplied) as shown below: Do not
connect any vehicle circuits together,
they are isolated for a reason.
