BLUE w/BLACK: Active output (-) Ignition 3 / Shock Disable Output
This wire provides a 300mA ground output that becomes active 3 seconds before the Remote Start system
initializes, and remains grounded while running plus an additional 4 seconds after the Remote Start system
turns off. In all of the applications described below, a relay will be required. The BLUE w/BLACK wire can be
used to accommodate the following situations:
1. Shock Sensor Bypass:
If there is Shock Sensor used with an alarm system and it is not shunted during the Remote Start activation
period, then vibration from the running vehicle can cause the alarm to trigger. In this case, connect the Blue/
Black Wire to terminal #86 of a external relay. Connect terminal# 85 of the relay to a fused + 12 volt battery
source. Cut the shock sensor trigger wire and connect one end of the cut wire to terminal #30 and the other end
of the cut wire to terminal #87a. Just before the Remote Start system is activated, the relay contacts will open,
preventing the shock sensor's operation until the Remote Start system shuts off.
2. 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, connect the BLUE w/BLACK wire to terminal #86 of an external relay. Connect terminal # 30 & #
85 to a fused + 12 volt battery source rated for a minimum of 25 Amp. Connect terminal # 87 to the third ignition
wire in the vehicle.
3. Transponder Key Override:
To bypass the system while the vehicle is operating under the control of the Remote Start system. Connect the
BLUE w/BLACKwire to the NEG trigger input of the accessory bypass.
BLACK w/GRAY: Diesel Wait To Start
For Diesel glow plug preheat circuits, this Wait To Start input will allow the ignition to keep the glow plugs active
for the vehicles automatic time out period before cranking the starter motor. If the BLACK w/GRAY is connected
to the glow plug wire, this will take precedence over the timing setting and the Gas/Diesel programming in the
feature programming chart. Use this wire if you do not want to set the timing of the glow plug preheat circuit as
shown in the programable features chart #8.
