Cory,
I have a 2001 ETH and that was the part number quoted to me today by Cummins. The parts guy stated that this part superceded all others. They wanted $40 for it. Believe it or not, the dealer only wanted $27... dunno. Oh yeah, Auto Zone only wanted $25. Guess where I'm going... every dollar saved buys me more toys/gadgets.
