They probably go in the frame somewhere. I have checked the parts cat. and i have a vent tube from the TC, but it doesn't say where it goes. My opinion is that the open end should be in the highest point possible, so i would run it along the firewall and in the engine bay somewhere.

 

If you look really close behind the front tire, you can see where mine is.
I never found an "actual" place to put it.

 

Hmm Ok. Appreciate the thoughts. Just seems strange that the guy I bought the Jeep from has them all just zip-tied right there. Then again he had an auxillry fan installed ran by a switch off the battery. It didnt work for me until yesterday, (was moving the vacuum bottle out of the front bumper and into the engine compartment) and in between painting the expansion tank rack I was going over things. I noticed that the ground wire for the fan was on top of the fan shroud with the screw ontop of it all, basically not completing the circut or very well. I swapped the ground wire in between the shroud and frame and presto. Guess it wont come in handy till next summer, but its one less thing. Whew, anyway, thanx again.

 

Its a vent line nik. Like fantic said, mount it high on the firewall.
