I don't have one installed myself, but I've seen pictures of them
installed in-line with the heater hose behind the air deflector behind
the shifter. I reckon there's enough straight hose there to cut out
and splice in the valve. I reckon it'd be POSSIBLE to rig something up
with the dash lever, but I'd sure hate to be the one engineering it
with off-the-shelf parts. Most people seem to use the additional valve
as a positive shutoff for the summer and use the OEM valve for
temperature control in the winter.

Just thinking out loud, but does anyone know why one couldn't relocate
the OEM valve to that spot there, behind the air deflector? That'd
certainly make it easier to futz with...
