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.
• Failure to use specified installation parts and/or hardware will void the product warranty!
• 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 manual states that this product may be mounted with suction cups, magnets, tape or Velcro®, clean the 
mounting surface with a 50/50 mix of isopropyl alcohol and water and dry thoroughly.
• Do not install this product or route any wires in the deployment area of your air bag. Equipment mounted 
or located in the air bag deployment area will damage or reduce the effectiveness of the air bag, or 
become a projectile that could cause serious personal injury or death. Refer to your vehicle owner’s 
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 
NEGATIVE (-) battery post.
• If this product uses a remote device to activate or control this product, make sure that this control is 
located in an area that allows both the vehicle and the control to be operated safely in any driving 
condition.
• Do not attempt to activate or control this device in a hazardous driving situation.
• It is recommended that these instructions be stored in a safe place and referred to when performing

Using appropriately 
sized wire, extend 
the input wires to 
fuse blocks installed 
at the battery.
Connect each fuse 
block individually 
to the Pos. (+) 
battery terminal.
Each input wire 
must be fused 
independently.

Wire Gauge Calculation Chart
To use this chart...
1. Determine the amount of current being drawn through the wire. Locate this 
number in the top row. If the current value is between adjacent values, use the 
higher number.
2. Follow this column down until the length of the installed wire is shown. If the exact 
length is between adjacent values, use the higher number. The wire gauge shown 
for this row represents the minimum size wire that should be used.
IMPORTANT! This product was designed to be configured using the WeCan system programming software. It can not 
be used as a stand alone module.
WARNING! All customer supplied wires that connect to the positive terminal of the battery must be sized to supply at 
least 125% of the maximum operating current and fused ‘at the battery to carry that load. DO NOT USE CIRCUIT 
BREAKERS WITH THIS PRODUCT!
Addressing - The network address for this module is pre-configured to be identified in the configuration software as 
“MODULE 1”. If two (2) REMOTE16 modules are installed, it will be necessary to cut the jumper wire located between 
J1-2 and J1-5, on one
 of the modules. That module will now be identified in the configuration software as “MODULE 2”.
