(I'll bet if you drop the special designation, life would improve.)

If you break out the multimeter you can tell if you are getting voltage
down the three other lines and what the resistance is like in the speed
load.  If you pull the plug off the back of the switch (like you would
have when you switched you can also test which is the 12v (bet it's the
RED one) and the others etc. 

I am also wondering if your car is putting out very much voltage, are
you getting 13.5v (or more) measured across the battery's posts when the
car is running?
