Before connecting this wire, remove the supplied fuse. Connect to the positive battery terminal or the constant
12V supply to the ignition switch.
NOTE: Always use a fuse within 12 inches of the point that you obtain (+)12V. Do not use the 15A
fuse in the harness for this purpose. This fuse protects the module itself.
When the system receives the code controlling channel 2 for longer than 1.5 seconds, the red/white wire will
supply an output as long as the transmission continues. This output is often used to operate a trunk/hatch
release or other relay/driven function.
IMPORTANT! Never use this wire to drive anything except a relay or a low-current input! The
transistorized output can only supply 200 mA of current. Connecting directly to a
solenoid, motor, or other high-current device will cause it to fail.

This system can control two common power door lock types without any additional parts! With certain vehicles,
or if an actuator is to be installed, either a 451M Door Lock Relay Satellite or two relays will be required.
IMPORTANT! If you mistake a Type C direct-wired system for a Type A positive-pulse system, the
module will be damaged!
