Sentinel HDX Quick Start Manual And Installation Manual - page 10
Electrical Harness Routing and Connection
The Sentinel HDx unit is designed to operate directly off of your vehicle’s 12 volt electrical
system via a (2) two wire installation. Most vehicles provide two basic types of 12 volt supply;
switched on and off with the vehicle’s ignition and always on. The HDx should always be
connected to the 12 volt always on power source. The basic Sentinel harness DOES NOT
include an inline fuse, so installations should always make connection at the vehicle’s fuse
panel or utilize an optional fuse harness assembly.
There are numerous options for connection to the vehicle’s fuse panel. Sentinel HDx provides a
basic tap for ATC/ATO sized fuses with the harness assembly. Refer to the diagram below to
help determine your fuse type.
Important: If you have any doubt as to your ability to safely install the HDx unit,
please consult a professional familiar with the electrical system of your vehicle’s
manufacturer.
1. Beginning at the mounted camera assembly, work back from the installation site to the
vehicle’s fuse panel.
2. Place the cable harness barrel connector into the mating receptacle on the top of the
camera assembly.
3. Securely route the harness wire behind trim work from the camera down to the vehicle fuse
panel. DO NOT remove the two magnetic assemblies from the camera end of the wiring
harness. They are required for EMI reduction. If the harness needs to be trimmed or
extended, do so at the opposite (fuse panel) end of the cable.
