not jump wires at the Ignition Switch: this
would compromise the OEM electrical system.
This wire will power the Heater Blower Motor.

Chassis ground
input
This wire must be connected to bare, unpainted
metal (the Chassis or the true Body ground). It is
preferable to use a factory ground bolt rather than
a self-tapping screw. Screws tend to get loose
or rusted over time and can cause erratic
problems.

Tachometer
input
This wire will allow the Remote Car Starter to
sense whether the Engine is running. The wire
requires at least 1.8 V (AC) and 1.6 Hz or faster
when the Engine runs at idle speed. Among
common references for the Tach wire are: the
negative side of the Ignition Coil, the Camshaft
sensor, the Crankshaft sensor or the Engine
Control Module (ECM).
