If you have the latest Gen IV BC version, look up Lars post regarding his installation. His post has several pics on the hoses layout. Just be warned, the hoses are longer than needed on most installations, ok my installation, so you may need to look at the layout closely to avoid areas where the hose is rubbing.
I need to update that thread, because me being me, I've changed a few things. Firstly though, I realize I never posted a photo of the receiver/dryer and related plumbing, which lives in the passenger fenderwell. So, here:
Other than keeping the heater inlet box, this is the exact dryer installation and hose routing that BCB suggests, per Jason.
As Stretch noted, some of the BCB supplied hose are longer (by a lot, IMHO) than necessary, which is one of the reasons I made my own. The other reason being there is no shop convenient to me that could make custom AC hoses, and I like doing things my own way when it doesn't add too much work.
All of my AC hoses including the ones I made myself more or less follow the BCB suggested routing. Or at least they did. I didn't like the way I ran the compressor to condenser hose, so I've since made a new one. Which required purging and recharging the system, oh joy. And I made things more complicated by being determined to keep the OEM heater air vent box, plus I put a fresh air inlet on the BCB-supplied heater air blank-off plate, which, now that I've driven it, I can say works pretty well.
