J1939 Type 2 (Green) Female to J1939 type 1 Male Adapter

The adapter below is a straight through adapter - all pins wired 1:1. It will work in most situations. We also offer other adapters below this one for use in specific situations where connecting all lines may cause communication issues or where the device being connected does not handle the new high data rate.

Starting in 2016 All heavy equipment vehicles are equipped with the new high speed J1939 Type 2 system. This system has Green colored connectors instead of the standard black Type 1. A type 1 connector cannot plug into a type 2, but the type 2 can plug into both.

The Green connector is available with a locking ring and without a locking ring. Rotating the locking ring when connected assures that the connector cannot come unplugged accidentally. The connector without the lock ring is pressure fitted and is more suited for a test or diagnostic environment where the connector is plugged and unplugged regularly. All of our Type 2 cables can be special ordered with the non-locking connector for an additional cost and lengthened delivery time. Contact us at sales@mefiburn.com for more information.
