| DEI 456B GM Data Interface - Park Avenue / Seville, etc. | ||||||||||||||||||
| The fast and easy way to hook up factory power door locks and controlling the factory security system! | ||||||||||||||||||
| The DEI 456B Interfaces with specific GM Buick Park Avenue, Cadillac Seville STS and Cadillac Seville SLS vehicles.
The 456B 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 door lock system through the existing factory data wire in the vehicle. The 456B also operates the smart dome light integration on some vehicles. |

Then connect the DEI 456B 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. | ||||||||||||||||||
