I bought the 6/12-volt motor from LMC quite a while ago. Two problems as I remember.

First, I had to use one of those hot wire ceramic resistors to clam the thing down when I was running at 6-volts. I don't remember a switch or resistor on the motor itself.

Once I got it going, the arm coordination seemed whacky. I laid with my head under the dash for a long time and figured that I had to lengthen an arm a bit. The 2nd picture shows the result. See the small gap in the original arm? I never did get 2 speeds, though.

Warning: All this is from a feeble memory!
