Section 1 Guidelines for the Installation of VIM Module and V7A
This document will serve as a guideline for the installation of a V7A and a VIM module. The proper methods for the
connection of the output from the VIM module must be determined by the installer at the time of installation. This
document will be divided into two sections. The first will focus on the installation of the V7A and the second will
focus on the installation of the VIM module. The V7A and the VIM will be paired at the time of manufacture and
should be kept together until they are installed in a vehicle.
The V7A and the VIM module communicate via a wireless connection using an encrypted serial protocol. While the
link is designed to be very robust, there are some attributes that must be considered when installing these devices
into a vehicle. It is assumed that both the V7A and the VIM module will be installed inside the passenger
compartment of the vehicle.

VIM Module
The VIM module will typically be installed in a location that allows easy access to the immobilizer device. The
following steps will allow for reliable communication with the V7A.
• Theunitshouldbeinstalledwithinthepassengercompartmentof thevehicle
• Theunitshouldbeconcealedinawaythatitisnotreadilyvisibletotheuserorathief
