I mention you Ben because I know you at least at one time had several
Behr Underdash unit, but the question is posed for anyone with a Behr
unit which is out to take a picture of, or who has a good memory to
describe a few things. Mine is missing some pieces, which is not going
to stop me, but if I knew what they looked like (or, better yet, if
anyone actually HAD these items for sale) it would be very helpful.

First off, the main unit (as you are looking at it from the interior
of the car) there are vents that come out left and right. I believe
the lower left vent goes all the way across the dash to the left hand
fresh air vent. I believe the double outlet above that goes to the
double vent that replaces the radio. Now the missing part... there is
apparently a (now missing) vent that goes to the right to the right
hand fresh air vent. I would love to know what this looks like, or as
I said, be able to purchase one. It looks as if the vent housing was
once glued to the plastic housing of the main unit body.

Secondly, there is reference in the instructions to adapter to the
left and right vents. Are these necessary? What do they look like? I
can confirm that 2.5 inch marine ducting will fit over a vanagon fresh
air outlet, but I don't know why I need an adapter or what the adapter
would look like.

Third, what about the plugs that cover the fresh air outlets in the
distribution box? I could saw up some wooden plugs and seal them with
foam, but it would be nice if there was a pipe cap or something that
would work.

Finally, is there anything that people do to the distribution box,
like seal off a flap or something, or do they just leave it as it is?

What fun, and I haven't even gotten to the wiring yet.

Thanks in advance,

Jim
