Fortress Technologies FS-50 manual Power Door Locks Wiring & System Types

Crimestopper Door Lock Accessories: CS-6600DLM:Dual-relayplug-in module for Reverse Polarity, Positive, or Aftermarket Motors. CS-6500DLI:Plug-in pulse inverter that converts the Negative outputs of the system to Positive type for Positive Door Lock systems.

CS-610S1:Aftermarket door lock actuator (motor).

POWER DOOR LOCKS: WIRING & SYSTEM TYPES

PIN 1: BLUE: (-) Negative pulse for UNLOCK

PIN 2: RED: 12V When using external relays (TERM 86)

PIN 3: GREEN: (-) Negative pulse for LOCK

DETERMINING DOOR LOCK TYPE: We recommend determining the type of locking system the vehicle has before connecting any wires. Incorrect connection may result in damage to the alarm and/or vehicle locking system.

Door lock information is provided as a guide. Your vehicle may be different.

Negative Trigger (-): Many Imports; Late model Ford & General Motors

Negative trigger door lock systems send a Negative (Ground) pulse to existing factory relays to lock and unlock the vehicle doors.

Positive Trigger (+): Many General Motors; Chrysler / Dodge / Plymouth

Positive trigger door lock systems send a Positive (12V) pulse to existing factory relays to lock and unlock the vehicle doors.

Reverse Polarity: Many Ford/Lincoln/Mercury/Dodge/Chrysler/Plymouth and early 90’s GM Trucks

Reverse Polarity systems use no relays, but instead the door lock/unlock motors are controlled directly from the lock and unlock switches in the door. The lock and unlock wires rest at Negative Ground when not in use. When the lock or unlock button is pressed, one of the circuits is “Lifted” and replaced with +12V causing a lock or unlock to occur.

Single Wire (Dual Voltage): Late model Chrysler/Dodge/Plymouth Vehicles, some 2000-UP GM

Dual Voltage systems have lock/unlock switches that send varying levels of Positive voltage OR Negative ground current to the SAME wire for both lock and unlock. When the vehicle’s Body Computer Module (BCM) or door lock module senses different voltages on this wire, the system will either lock or unlock. Single wire door lock systems require relays and resistors.

Databus Systems 2003-UP GM Trucks & SUV’s, ‘96-04 Jeep Grand Cherokee

Databus systems send low current “Data messages” to the door lock controllers on a network in order to lock and unlock the vehicle. To install aftermarket systems in these vehicles, an interface module is required that converts the regular lock/unlock pulses into “Data messages” to allow locking & unlocking. Interface modules are sold separately.
