Included tranny supply, seat air, all the air tank and dryer lines, lines going to the abs, the tractor air suspension, the horn, the fifth wheel slide, power divider, and tractor leveling valve. also replaced the cab leveling valve as it was falling apart. The lines in the dash, the line to the fan clutch, and a couple lines around the drive axles are all that isn't new. Also replaced all the fittings and the bulkhead fittings. A little bit of a pain, but I found a few badly worn lines that would have leaked shortly, and my E-6 was making noise so that I was pretty sure it was going, and my tp-5 wasn't doing its job. So since the tranny, drive shafts, and exhaust were out, I figured "while I'm there..."

I run into things - like the seat air for example, that I have no clue to the why... It currently comes off a pressure protection valve mounted on the e-6. But then there's an air seat output on the manifold that's plugged. Why? is there some advantage or reason? That's one of the protection valves that's leaking, so is there a benefit the way it is that I shouldn't just remove it completely and run the line from the manifold port already labeled air seat?

On another note, I put the passenger window down for the first time, and see that it goes between the panes on the view window... What a stupid design. With as much as I still need to do with the truck, I'm wishing I had just bought something from the 90's.

My seats are plumbed the same way. I replaced the check valve as well. And my manifold has the plug also. No idea why they do it that way unless there's no valve in the dash and they decided to mount it on the E6 as an afterthought. I dunno.
