Wiring
Securely attach cable connectors to receiver (black 12-pin connector),
in-cab display (gray 12-pin connector) and telematics module (18-pin).
Securely route all cables to a common location inside the cab,
preferably close to fuse panel with truck electrical connections (+12V
battery, +12V ignition switched and vehicle ground).
Use only power cables with copper conductors size 20 AWG minimum
to 16 AWG maximum (0.82 mm
2
to 5.26 mm
2
). Due to temperatures in
truck cabin, cable rated 176°F (80°C) or higher is recommended.
Cut to length and strip individual wires as described in the following
sections.
4.8.1 Wiring DC Power
An overcurrent protection device (fuse) must be installed on the
supply side of the ignition switched and battery inputs, with a fuse
