[s-cars] Headlight motors, type 44 ... wiring?

This is going from old memory, so can't gaurantee it's 100% accurate.  First
of all, there is no relay needed.  The switch is numbered 1-3, but is
variable in between rather than discrete steps (doesn't mean there may not
be detents at the 1, 2, & 3 positions).  Just like the seat heater
controls.  In the case of the headlight motors, I believe what happens is
that the motors have two positive signals working against each other.  The
controller lowers the voltage of one of the leads, which allows the motor to
move in one direction.  As you move the controller back the other way the
voltage increases and the motor moves back.  At least that's my
understanding of how it works, which could be all wrong.  However, I can
tell you that when I wired up the system on my VW Corrado I used complete
European wiring harnesses and no relay is anywhere in the mix.  And the
system is completely variable between 0 and 3.

Take a look at the back of the switch and look at the numbers for each of
the pins.  Not the 1-6 or whatever number of pins there are, but the
terminal circuit designation (i.e., 15, 31, 56a, etc).  You should find some
corresponding numbers on the motors.  I believe these are molded in on both
