I would suspect yours is 1708 since your coach was actually built during calendar year 2002. J1939 Deutsch connectors have 9 pins. J1708 have 6 pins so it should be easy to verify.
Oops, I just reread your post and you have the square connector. You may have to count the wires on the rear of the connector. The J1708 should have 4 wires and the J1939 should have 7 wires.
