Chassis Ground Connection Detail
Brown w/ Black Trace Wire: Positive Inhibit Input
The Brown w/ Black Trace wire provides an instant shutdown for the Remote Start Control module when-
ever it gets + 12 volts. If the Brake lights switch in the vehicle switches + 12 volts to the brake light circuit,
connect the Brown w/ Black trace wire to the output side of the brake switch. This will allow the Remote
Start to shut down if an attempt is made to operate the vehicle without the key while running under the
control of the Remote Start. In most vehicles, in order to shift into gear, the brake pedal must be de-
pressed. The brake input will in turn cause the remote start unit to shut off. See detail in the following
diagram for wiring the brake light circuit.

Green w/ Orange Trace Wire: Tachometer Input Signal
This wire will continually monitor the engine's tach rate while the unit is under power of the Remote Start
module. This wire will be routed to the vehicle ECM tach input or through the firewall into the engine
compartment and connect to the negative side of the ignition coil. This Remote Start unit learns the tach
rate of the vehicle and in most cases will operate properly from one multi coil pack regardless of the number
of cylinders. If the vehicle has a single coil unit for each cylinder, it may be necessary to connect this wire
to more than one cylinder for proper tach reference. See multi coil wiring detail shown later in this manual
for additional information.
Note: For Hybrid mode, Bank 3 feature selection 5, this connection is not used, the unit will start the
vehicle and run the allotted time based on feature selection and crank duration.
