Introduction
This document identifies all the harnesses available in MyAdmin, and the harnesses available by special order. This document also provides an overview of each harness:
- A description of the harness (as seen in MyAdmin);
- The length of the harness;
- The purpose of the harness;
- The GO device supported by the harness; and
- The renamed or replaced harness.
Naming Conventions
In June 2014, we updated the harness naming convention. This section outlines the new naming convention and provides definitions for each character or group of characters.
Harnesses all start with an HRN prefix followed by 6-character names, as defined below. All characters are alphanumeric and, to avoid confusion, no I’s or O’s are used.
Examples:
- HRN-DS09T2
- DÂ represents a Deutsch connector.
- SÂ represents a Standard OBD, Deutsch, or FMS connector.
- 09Â represents 9 pins / wires.
- TÂ represents a T-harness.
- 2Â represents a length in the range of 12-24 inches or 30-60 cm.
- HRN-BS16S4
- B represents OBD type connectors.
- S represents a Standard OBD, Deutsch, or FMS connector.
- 16 represents 16 pins / wires.
- S represents a straight harness.
- 4 represents a length in the range of 36-48 inches or 120-152 cm.
- HRN-CW03S3
- CÂ represents a Custom harness.
- WÂ represents a Harness with exposed wires.
- 03Â represents 3 pins / wires.
- SÂ represents a Straight harness.
- 3Â represents a length in the range of 24-36 inches or 60-90 cm.

Installation Notes for All Harnesses
! IMPORTANT: For heavy-duty trucks, always use a vehicle-specific harness when offered by Geotab or the vehicle manufacturer (see Harness Identification and Application [PUB] and Harness Assessment Cheat Sheet GUIDE V2.0 [PUB]). Where a heavy-duty truck-specific harness is not offered by Geotab or the vehicle manufacturer, use the adapter harness (HRN-CG13S1) for any 16-pin (OBDII) installation method to avoid possible GO device damage. |
✱ NOTE: If a longer length is required to facilitate installation, connect a straight harness to a T-harness or another straight harness — where indicated below. The total harness length must not exceed 2 meters (or 6.5 feet). |
✱ NOTE: Regardless of the length, two T-harnesses CANNOT connect to each other. Connecting two T-harnesses, or any two harnesses that exceed 2 meters, compromises the integrity of the data and may cause issues with the vehicle’s Engine Control Unit (ECU). |
! IMPORTANT:Â Some vehicles have multiple diagnostic connectors to choose from when installing a GO device.. For further information to compare and contrast OBD-II and RP1226, please visit the following link: https://gtb.page.link/hKF7. |
