What should I look for when considering the J2K100 gateway/bridge?

Technicians can look for an engines diagnostic connection in close proximity to an engine ECU. Generally, most diagnostic connectors used by the engine manufacturers are standard and manufactured by Deutsch connector company. Under article attachments, Maretron provides a printable cheat sheet to help technicians identify engine J1939 connections and the engine connectors known pin designations. Note: take caution when tampering with Engine ECUs, always refer to the engines service manual and or consult the engine manufacturer for the correct connection to use for the J2K100.

Maretron strongly encourages to consult with their engine's manufacture to validate your specific setup, providing the VIN # or Serial # of appropriate equipment and confirm where to safely access J1939 data if available.
