Blue Wire:
(-) Ground Instant Trigger Input (Zone 2)
This wire is the ground trigger input wire for hood/trunk pin switches.
White/Green Wire:
(-) Diesel Wait to Start Input
In diesel vehicles, it is necessary to interface with the wire that activates the "Wait to Start" light in the dash-
board. 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 DC voltage (12V or 20V).
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 0 Volts until the light goes out, and then reads 12 Volts, you have isolated the
connection 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 dash-
board. In most diesel vehicles the wire is negative (Ground Turns On the Bulb) and this wire can be directly
connected to the vehicle. If the vehicle uses a positive wire (12V to Turn the Bulb ON) a relay must be used to
change the polarity.
Green Wire:
(-) Negative Door Switch Input (Zone 3)
This wire is the ground trigger input wire for a negative door pin switch. Locate the “common wire” that con-
nects the door pin switches, and make the connection of the Green wire here.
Violet Wire:
Positive Door Switch Input (Zone 3)
This wire is the positive trigger input wire for a positive door pin switch (typical to Ford Motor Co.). Locate the
“common wire” for all door pins and make the connection of the Violet wire here.
