When the ignition key "on", the Yellow wire has voltage, and the following can occur:
*
Automatic Transmitter Verification will operate when the ignition switch is turned "on".
*
The security system cannot become armed, either actively from the transmitter or passively from Last Door Arming.
*
The Valet Switch can be used to disarm an armed or triggered security system within 5 seconds of turning the ignition switch "on".
*
If the system has a Zone Violation code stored, turning the ignition switch "on" clears the code.
*
Remote trunk release will not operate unless a door is open.
*
If the parking lights are on for the 30 second period as a result of disarming the system, if the ignition is turned "on" during this time, they will turn off.
CONNECTION: This connection, like the Constant Power and Starter Disable, are best made as close to the ignition switch as possible. If not using a
Quick Interconnect Harness, follow these steps:
At the ignition switch wiring harness, locate the primary ignition circuit. Primary ignition has 0 volts when the ignition key is in the "Lock", "Off" and
"Accessory" positions; and 12 volts in the "Run" and "Start" positions. When the correct wire is located at the ignition switch harness, securely splice the Yellow
wire to it. Not using the primary ignition wire can cause problems with features such as Last Door Arming Doors Lock At Ignition "On", and Unlock At Ignition
"Off".
Grounded Output for Starter Interrupt
The Orange wire is for a starter disable socket and relay. The function of this wire is to provide a constant 500ma ground output whenever the security
system is armed. This ground output supplies one side of the relay's coil. The other side of the relay coil will be supplied with positive voltage from the
ignition switch, but only if the ignition switch is turned to the "start" position. If this occurs, the coil will energize, triggering the relay, which in turn will open
the starter circuit. The starter interrupt prevents the vehicle from starting only if the security system is armed (including while the security system is
triggered) and will draw current from the vehicle's electrical system only if an attempt is made to start the vehicle.
CONNECTION: This connection, like the Constant Power and Ignition Power circuits, are best done as close to the ignition switch as possible. We urge
you to use an Omega Research and Development Quick Interconnect Harness. A Quick Interconnect Harness is an adapter wiring harness which plugs into
an existing pair of the vehicle's stock connectors, with circuits needed for the system branching off to a connector which plugs into the security system. If
you're not using a Quick Interconnect Harness, follow these steps:
To interrupt the vehicle's starter circuit, the starter wire must be located and cut. We recommend that this be done as close to the ignition switch as
possible. Use a voltmeter, not a test light, to find the correct wire. This wire runs from the ignition switch to the starter solenoid. CAUTION! Avoid the
airbag circuit! Improper use of a test light can cause deployment of the airbag, which may result in bodily injury! Test lights can also damage expensive
onboard computers and associated sensors.
