Gm Vats Key Override - Viking RX300 Installation Manual

If the vehicle has transponder system installed, you will need to by-pass the system while the vehicle is
operating under the control of the Remote Start Unit. To do this:
1. You will need a transponder key that's already programmed to the vehicle.
2. Remove the trim around the ignition switch.
3. Wrap a thin (28 - 30awg) wire tightly around ignition switch 6 to 8 times and secure it.
4. About 6"down line make another loop of approximately 2"diameter.
5. Place the key inside this loop and secure it to the loop.
6. Connect on end of the (28 - 30awg) wire to pin (87) of the relay module.
7. Connect the other end of the loop wire to Pin (30) of relay module.
8. Connect the pin (86) of the relay module to the ignition wire from the ignition switch.
9. connect the pin (85) of the relay module to the H5/2 Yellow wire of 5-pin mini white connector.

GM VATS KEY OVERRIDE:

If the vehicle has the General Motor VATS system installed, you will need to by-pass the system while
the vehicle is operating under the control of the Remote Start Unit. To do this:
1. Measure the resistance of the resistor pellet on the ignition key then select a resistor within 5% of the
key's value.
2. Locate the pair of VATS wires in the vehicle, usually a pair of thin gauge wires running from the
ignition switch to the VATS control module.
3. Connect the YELLOW wire from Remote Start Unit to TERMINAL #85 of an external relay. Connect
terminal #86 of the relay to a fused +12 volt.
4. Cut (#1) wire (as shown), and connect the ignition switch side of the cut wire to terminal #87a of the
relay. Connect the other side of the (#1) wire to terminal #30.
5. Connect the previously selseced resistor from terminal #87 to the second(#2) wire (as shown).

H5/3. WHITE WIRE – (-) 200ma PROGRAMMABLE OUTPUT
Dome Light Control Output
This wire becomes grounded when the dome light controls circuit active. The current capacity of this wire is
200mA. This wire can control the operation of the interior lights. An optional 10 Amps relay can be used to
this system for interior lights operation.
a). Upon disarming, the interior lights will remain on for 30 seconds.
b). If the vehicle is violated, the interior light will flash for the same duration as the siren.
Horn Output–
(See Alarm Feature III - 2 Programming)
This wire is provided to use the existing vehicle's horn as the alarm system's optional's warning audible
device. It's a transistorized low current output, and should only be connected to the low current ground
output from the vehicle's horn switch. When the system is triggered, the horn will sound.
Factory Security Rearm Signal Output–
This wire is designed to rearm a factory installed security system. This wire will supply a pulse whenever
the remote start times out or is shut dowm using the transmitter and remote door locking..
Ground Output During Start (Crank) –
This wire will provide a 200mA ground output while the starter output of the remote start unit is active. This
output can be used to activate the Crank Low/Bulb Test wire found in some GM vehicles. This wire is also
referred to as the ECM wake up wire in some vehicles.
H5/4. PINK WIRE – (-) 200ma PROGRAMMABLE OUTPUT
2 Steps Unlock Output –
The 2 steps unlock feature will work for the most fully electronic door lock circuit. The vehicle must have an
electronic door lock switch (not the lock knob or key switch), which locks and unlocks all of vehicle's doors.
