3Speeds are approximate and may vary slightly depending on application Wiring to a door lock motor. Dakota Digital RLY-2 relay pack shown. To PAC-3500Lock output. FUSED 12V POWERTo PAC-3500Unlock output. The wires between the switch and the motor will need to be cut, and the relay pack wired in between as shown. Fused 12V power. MOTORMOTORSWITCHPURPLEGREENBROWNWHITEBLUERELAYREDsmall wireGREENPACKBLUEsmall wireDUAL+12v on lock+12v on lock 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 gear input. Switch 1 Suicide safety pin select switch 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. Switch 2 Unlock mode select 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 2 is off, the doors will only be unlocked when the ignition is turned off. Switch 3 Lock mode select 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. 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 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. 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 other side to fused constant +12v. UNLCK Negative output used to drive relay for unlocking doors. Connect one side of unlock relay coil to this terminal and other side to fused constant +12v. WARN Negative output used to drive bulb for warning output, only used in suicide pin mode. It is capable of switching 0.25A, equivalent to a 3 watt 12V bulb. Connect one wire from bulb to terminal and other wire to fused +12V. If a larger or high power indicator is used a relay should be used to turn on the light. In this case connect one side of the relay coil to the WARN terminal and the other side to fused +12v. The relay contacts will then be used to power the light. Any 12v automotive relay can be used, such as the Dakota Digital, RLY-1 30A relay. SPD Speed input required only if using lock on speed setting, leave unconnected otherwise. For 2 wire pulse generators connect one wire to ground and the other wire to SPD terminal. If the signal is being shared by a cruise control or ECM, make sure they all use a common ground for the pulse generator. For 3 wire Hall-effect sensors, refer to the installation instructions for the sensor to determine wire color code. Most 3 wire sensors use the following color code: RED – power, BLACK – ground, WHITE – speed signal. For speed sensor integrated into a vehicle wiring harness, consult a service manual to determine the color code and location of the speedometer signal. L PIN Required if suicide safety pin mode set (switch 1). If not used leave & R PIN unconnected. These are inputs from the switches on the suicide safety pin assemblies. The switch will connect the R PIN or L PIN terminal to ground when the pin is fully actuated. If either of the switches fails to close when pins are to be locked, the warning tone and output are activated. IGN Should be connected to have +12v when key is ON. The auto-lock module will not operate unless it receives the ignition signal. GEAR Required if set to lock or unlock using park signal and using Dakota Digital gear sender (GSS-1000, GSS- 2000…) in 1-wire gear signal mode. Connect the 1-wire gear signal wire from sending unit to this terminal. If not used, leave unconnected. PARK Required if set to...
