Indicator LEDs

The green LED will turn on when the auto-lock module is receiving a signal from the ignition terminal. It will begin
flashing if a vehicle speed signal is present at the SPD terminal.
The red LED will turn on solid if there is a +12v park signal. It will flash if it is receiving a park signal on the 1-wire

Switch 1 Suicide safety pin select switch

Switch 2 Unlock mode select

When switch 2 is off, the doors will only be unlocked when the ignition is turned off.
Switch 3 Lock mode select

When the switch is off, the auto-lock unit will lock when the vehicle exceeds the speed selected by switches 4-6.

Switch 4-6 Speed select

PWR Provide fused constant battery power (+12v) to this terminal.
GND Main ground for auto-lock unit. Poor ground connection may cause the system to not operate properly.
LOCK Negative output used to drive a relay for locking doors. Connect one side of lock relay coil to this terminal and

UNLCK Negative output used to drive relay for unlocking doors. Connect one side of unlock relay coil to this terminal

gear input.

When turned on (switch toward case), this switch selects the Suicide safety pin mode of operation. This mode
enables the warn output and the internal warning tone. It also enables the door pin inputs. After the auto-lock unit
attempts to lock the doors, it checks the suicide safety pin switches (door pin inputs). If one of the pins fails to
lock, the tone and warning output are activated. The tone and warning output will also be activated if the door pins
become unlocked while the vehicle is still in lock condition (over set speed or out of park).
The tone and warning output will remain activated until the pins are manually operated to lock or the auto-lock can
reattempt and succeed to lock the pins.

When switch 2 is turned on, the auto-lock unit will unlock the doors when it receives a park signal from either the
+12v park input or the 1-wire gear input.

When switch 3 is on, the auto-lock unit will lock the doors when there is no park signal on either the +12v park
input or the 1-wire gear input.

These switches are only valid when the auto-lock unit is set to lock on speed signal by turning switch 3 off.
Different speeds may be selected for the most common speed sender types (see chart on first page). The speeds
in the chart are approximate and may vary slightly depending on application. When the speed set by these
switches is reached the auto-lock unit will attempt to lock the doors.
