Safety First

This document provides all the necessary information to allow your Whelen product to be properly and safely installed.
Before beginning the installation and/or operation of your new product, the installation technician and operator must
read this manual completely. Important information is contained herein that could prevent serious injury or damage.

Proper installation of this product requires the installer to have a good understanding of automotive 
electronics, systems and procedures.

If mounting this product requires drilling holes, the installer MUST be sure that no vehicle components or 
other vital parts could be damaged by the drilling process. Check both sides of the mounting surface 
before drilling begins. Also de-burr any holes and remove any metal shards or remnants. Install grommets 
into all wire passage holes.

If this product is mounted with tape or Velcro™, clean the mounting surface with a 50/50 mix of

manual for the air bag deployment area. The User/Installer assumes full responsibility to determine proper 
mounting location, based on providing ultimate safety to all passengers inside the vehicle.

For this product to operate at optimum efficiency, a good electrical connection to chassis ground must be 
made. The recommended procedure requires the product ground wire to be connected directly to the

located in an area that allows both the vehicle and the control to be operated safely in any driving 
condition.
