I just replaced my heater core in my 2002 F-150. All I have left is to hook up the two new hoses. The only thing is that a couple of years ago I had the mechanics at the shop BYPASS the heater core. So,I cant just look at the old hoses. Is there a diagram or pictures that someone can show me? I'm guessing one is an intake and one is an outtake. I don't want to hook them up backwards. Thank you in advance.

 

It doesn't really matter if they are backwards, but the hose from under the intake manifold goes to the right if looking at the firewall.
