DEI 455J Jeep Grand Cherokee Data Interface, 1999+
The fast and easy way to hook up factory power door locks and controlling the factory security system!
The DEI 455J Interfaces with the 1999+ Jeep Grand Cherokees.
The 455J converts the signals from keyless entry, alarm, and remote start systems directly into signals that can be understood by the vehicle's data bus system.
This allows interfacing with the factory security and lock system through the existing factory data wire in the vehicle.
The 455J controls the door lock operations including locking, unlocking, and driver's door only unlocking. The 455J also provides control of the factory security system. The factory security system can be armed and disarmed when locking or unlocking the doors, or disarmed when remote starting without unlocking the doors, so the vehicle remains secure.
The 455J also operates the smart dome light integration on some vehicles.
The DEI 455J harness wires connect to the DEI (or other brand) CPU alarm, keyless entry, or remote start Door Lock / Unlock Outputs. Then connect the DEI 455J Data Bus Output to the vehicle's Data Bus wire at the Diagnostics Connector located at the bottom of the dash on the driver's side. That's it! It's that easy.
