Door lock systems vary by vehicle and manufacturer. In order to connect the door locks,
some vehicle will require addition parts such as actuators, resistors, or relays. For help
identifying the type of lock system in your vehicle please refer to our vehicle wiring
information on our website at www.designtech-intl.com
Caution: improper connection of unit to door lock system may cause
damage to unit or vehicle. Type A and Type C systems may look
similar, but if the unit is connected to a Type C configured as a Type A.
Damage will result. Always use fuses when using external relays. We
suggest a maximum of 15A fuse.
Type A : Positive
This system supplies a 12V pulse from the factory switch to the factory relays. IF you
measure the resistance between the lock/unlock wires and ground WITHOUT pressing the
door lock switch the resistance should be more than 50 ohms. If the resistance is less you
may be on the wrong wire(s) or you may have a reverse polarity system. SEE REVERSE
POLARITY. For positive trigger systems, connect the unit's outputs to the Lock/Unlock
wires of the vehicle. No additional parts should be needed.
