Some of you know more about the Taco than me so what is this lone hose?

As I relocate the tranny breather to higher ground, I notice this hose/tube sticking out on the passenger side. It doesn't appear to connect to anything. Any ideas?

TIA!

Taco info: 2005 V6 4x4 6-Speed

 

AC condenser drain. You should see water dripping from it when running your AC for an extended period of time.

 

Ac condensate drain. It Just drains moisture from your ac evaporator

 

Thank you, knowledge is good!

 

I'd put an extension on it and run it around the frame so the moisture doesn't drip on it.

 

Agree that is one of the high rust spots on the frame...I went to a parts store, got a double end barbed fitting and a few very of vacuum line....zipped tied it together and routed the hose down along the firewall to the frame and zipped tied it in place so that about an inch of hose is below the frame.
