Design Engineering DEI 451M Door Lock Relay Module with Resistors

The Design Engineering DEI 451M is a pre-wired door lock relay module designed to interface aftermarket alarm systems, remote starters, and keyless entry systems with vehicle door lock mechanisms. This versatile module includes a comprehensive resistor pack for compatibility with modern vehicle door lock systems.

Key Features:

• Compatible with most Directed Electronics remote start and security systems
• 3-pin plug interface for quick connection to DEI systems
• Dual 40-amp built-in relays for reliable operation
• Interfaces with electric power door lock systems drawing 30A or less
• Supports both relay-controlled and direct-wired reversing-polarity door lock types
• Includes 27 common resistors for one-wire and resistor-type door lock systems
• Pre-wired assembly with labeled wires for straightforward installation
• Solid-state design for enhanced durability and longevity
• Requires alarm-supplied momentary negative pulses for operation

The DEI 451M simplifies integration of aftermarket security and remote start systems with factory door lock mechanisms. The included resistor interface pack accommodates newer model vehicles with specialized door lock requirements, making this module a time-saving solution for professional installers and DIY enthusiasts alike.
