Door triggers

The door trigger is the circuit in the vehicle that tells the dome

light to come on when the door is opened. This wire can be

either a positive 12 volt polarity or more commonly a negative

ground polarity, the door trigger wire is mandatory for all secu-

rity systems and can usually be identified on

www.diyrattler.com. Using the information sheet for your

specific vehicle locate the suspect wire, if the door trigger listed

for your car is a negative type door trigger place the red lead of

your meter to a constant 12 volt source and secure it, take the

black lead of the meter and probe the suspect wire with the door

open, you will see 11.00 to 13.00 volts appear on the meter,

secure the black meter lead to the suspect wire and close the door

with the display on the meter visible, if you have the right wire

the voltage will drop to 0.00 volts, open the passenger door to

verify that the wire sees both doors. Once confirmed solder the

GREEN (H1/5) wire on the 12 pin harness to it and cover the

connection with black tape.

Some vehicles (mainly FORD) have a positive 12volt door

trigger if this is the case in your vehicle place the Black lead of

your meter to chassis ground and secure it, place the Red lead

of your meter to the suspect wire with the door opened the

meter should read 12.00 to 13.00 volts secure the red lead and

close the door with the meter display visible, when the door is

closed the meter should read 0.00 volts, open the passenger side

door and the meter should read 12:00 to 13:00 volts. Once

confirmed solder the VIOLET (H1/7) wire to it and cover the

connection with electrical tape.
