We've finally had some days in the 30's in Milwaukee area, so it's got me
tempted to start a couple of projects I've put off for a bit because of cold
weather - One is to replace a leaky slave cylinder, I think I've got that
covered (thanks to a recent thread), but will mail with any problems I run
into...  The other project is to install a rear heater unit that I bought
from someone on the list, into my van - an '82 Diesel.  The question I have
is: where do the coolant lines typically go through the fire wall, and where
do they splice into the heater hoses?  I've got an idea where to go through
with them (near where the air intake hose is for the auxiliary heater), but
thought I'd see if someone knew off hand (I wouldn't expect anyone to get on
their back in the cold and check) where the hoses ran.
Where is the unit itself usually located - passenger, middle, driver side
(U.S.)?
How big an in-line fuse should I use?  I'm probably just hooking up high
speed for now on a simple toggle switch..
Anything else I'd be forgetting?

Thanks,
Chris
