I am looking at the old unit still installed. I don't see the second line connector. I only see the 1 coming out of the top of the condenser. I don't see the second on with the longer connector coming out that I see on the replacement unit I purchased.

There is a label that is maybe on the old unit or what is is mounted to. Not sure. But the label reads:

The second line coming off W8000061 condenser is attached to the receiver drier. The part # W0000720 that you found is for the transmission oil cooler.
In need of a W8000061

Condenser for your VIN is W8000061 and engine oil cooler is W8000080, they are stacked.
I have a 2002 Mountain Aire that needs a new ac condenser and related parts, will this fit? ( Robert Pulliam , 08/07/2018 )
Yes this is the correct condenser for 2001-2004 Workhorse chassis.
