[Roadsters] dash heater/defrost controls early 67 roadster

[Dave]

hi, all.

making progress.  but there is no info on this particular area.

Ibm trying to figure out

1.  where do these cables go to?  I can guess that one goes from cold to hot
goes to the heater control valve in the engine compartment.  and the one
labeled defrost b that goes to both? of the valves up in/under the
dashboard?  The top two, Ibm clueless.  they say bopenb and bshutb
what?

connect to ?  and from which lever?
