YELLOW: (+) Brake pedal input.
Connect to the brake pedal wire that shows +12V when the pedal is pressed. The
brake pedal input functions as a safety shutdown and must be connected.
VIOLET/WHITE: Tach input.
Connect to the vehicle's tachometer wire or an injector wire if the tach wire is not
available. See Installer Programming Step 13 to program the tach reference after
installation. If a suitable tach wire is unable to be located, the Tachless mode may
be programmed to operate without using this wire. Note: the Tachless mode is not
recommended for extreme temperture climates.
YELLOW/BLUE: (-) Auxiliary 2 output 500mA.
Connect to a relay for an optional feature such as a linear actuator, headlight circuit,
window module, or etc. This auxiliary output can be programmed for momentary,
timed, or latched activation.

Connect to a relay for optional dome light supervision upon disarming the security
system. (See Dome Light Supervision diagram for assistance.)

Connect to the wire that shows ground when the trunk/rear hatch is open.
GRAY/BLACK: (+) Glow plug (wait-to-start) input.
Connect to the positive glow plug wire of diesel engine equipped vehicles. This
wire should show +12 when the wait to start light is on, and will show ground when
the light turns off. For vehicle's that show ground while the wait to start light is on,
use a relay to invert the polarity. See Glow Plug Relay Diagram.

prove a ground output upon remote start activation, and will remain grounded until
the remote start is shutdown.

Connect this wire to bare metal, using a lock or star washer to prevent the screw
from coming loose. If possible, use a factory bolt, rather then a screw.
