I just now got to the point where I could lift the heater core of my 90
clear of its mounts... except for one thing: the wires that power and
control the heater motor.
Is there a connector I am not seeing? Do most people just cut them and
solder them back later?

I read everything I could find on the list about removing the dash and
heater, and because of that information it was a very quick job, no problems
at all. Until these wires!

Also, what is the tall silver electronic box that bracket to the crossmember
behind the blove box and just to the right of the heater plenum? It has a
bunch of wires going to it.
