REM-4D 

REMOTE CONTROL  

DOOR LATCH OPENER SYSTEM 

 

INTRODUCTION

 

 
 

Thank you for purchasing the REM-4D Remote Control Door Latch Opener 

System from Dakota Digital, Inc.  This, along with many other products that Dakota 
Digital, Inc. has to offer, represents the latest in electronics technology for the street rod, 
classic car and truck, and any custom vehicle. 
 
 

The REM-4D Remote Control Door Latch Opener system comes complete with 

receiver, two key chain transmitters, wiring harness, emergency release switch, and 
three door opener motors.  It is installed to remotely release the driver's and 
passenger's door independently along with a third channel to release a trunk, rear door, 
or whatever.  A safety feature disables the system when the ignition is on to avoid 
accidental door opening during vehicle operation.  Two internal door release buttons 
can be wired into the system for removal of inside door handles as well.  An emergency 
release switch can be concealed on the underside of the vehicle should the door ever 
be closed with the motor running and you on the outside.  Pressing this button will allow 
reentry to the vehicle even though the remote control system is disabled. 
 

INSTALLATION

 

 
 

While installation of the REM-4D is very straightforward, paying a little attention 

here and planning out how the system will fit into your specific vehicle will save some 
time in the long run.  First, determine the best mounting method for the door motors 
within the doors.  The pull (or push) on the original door latch or newer bear claw latch 
should be as straight as possible.  Securely mount the motor and route the connecting 
rod as pertains to your specific situation. 
 
 

The receiver should be mounted under the dash up on the fire wall for best 

access to wiring.  The kick panel is also another good location for the receiver. 
 
 
 
 

Connect the REM-4D system as is shown in the wiring diagram.  While the wiring 

diagram is self explanatory, there are several key areas to pay particular attention to.  
First, the 12 volt source should be able to supply up to 10 amps (needed if two or three
