HRN-BD16S1 Installation Guide

The HRN-BD16S1 is specifically intended for vehicles that have a master power battery disconnect switch on the +12/24V, and

are using the T-Harness. Do not use this harness for Ground switched battery disconnects, or a 3-wire HRN-CW03K3 harness.

Successful installation of any device or equipment requires knowledge of the installation and device requirements. This

information is obtained by reading the device documentation and by speaking with the customer to understand their

requirements.

Installations should never be performed without first reviewing and understanding the device documentation and customer

requirements.

Note: The master power switch may disconnect the negative or the positive battery terminal.

NOTICE: Never assume polarity, and never assume that all vehicles are identically wired.

NOTICE: Connections at these master-power switches are often exposed and must be properly protected from corrosion. We

recommend you use loom to protect cable runs, as well as dielectric grease, heat shrink, and self-fusing tape at connections.

Any direct-to-battery connections also require wire and corrosion protection.

WARNING! It is important to understand the risks involved when bypassing a master-power switch. Improper grounding, lack

of grounding, or improper fusing can lead to death or serious personal injury. The bypass must not inadvertently provide an

alternate path for other vehicle circuits to power. The client must be informed and involved so that they understand and can

approve the installation.

1) Confirm vehicle Master power switch is + positive switched. This

is done by metering between the positive (J1939) pin and the

chassis, and toggling the master power switch. If the vehicle is

ground switched, the HRN-BD16S1 cannot be used.

2) Connect the T-Harness 16 pin connector to the plug

side of the HRN-BD16S1.
