Magnetic Switch and Relay Circuit

The circuit is pretty basic. A magnetic switch is mounted underneath the shifter.

The magnet is mounted on the shifter arm. When the shifter is directly over the

magnetic switch (neutral position) there is continuity between the terminals of the

magnetic switch. Any other position besides neutral results in an open circuit at

the magnetic switch. The magnetic switch is connected to a SPDT relay so that

when the switch is closed (neutral), the relay coil is energized by ignition voltage

and the common output (pin 30) is connected to an open circuit (pin 87). If the

car is in any gear, the relay coil is not energized and the common output (pin 30)

is connected to ground (pin 87a). If there is a diode connected across the relay

coil REMOVE IT to avoid ground noise that could trigger your Remote Top

Interface circuits.

The common terminal (pin 30) is connected to the stock Theft Alarm Relay at

connector C56-3 (G-B wire). When this wire is grounded, the Starter Relay is

disabled.

Make sure the Ground connections in this circuit are FIRMLY attached to the

bare metal of the center console. It is best to select a different location than the

one you used for the Remote Top Interface Module ground.
