Now for the heater hose questions.
In the link posted above for 4crawler it states a hose used for the rear heater. I didn't know we had rear heaters. I bought mine gutted for the most part so maybe that is why. Come to think of it, I think I remember seeing one in the junk yard that had a heater control at the back bottom of the center console. If I don't have that, where is the heater hose that went there going to haha. Maybe I have an extra hose somewhere not being used or the previous owner added it into the dash heat I dunno yet. I am going to try and find it so I can run a hose to the back seat area to suppy heat better and quicker for when my son or dogs are in the back. Maybe I can hook a valve to it as well to close it when no one is back there which could provide better heat for me from the front. I dunno yet, just thinking out loud.
