yes, you can just clip a wire from the body of the unit to ground and then touch the lead wire to the + with the switch in one position then change the switch and touch the + lead again ... hold the motor so it doesn't jump, they do have some torque .... and there should be 3 positions of the switch, off, on, high
you do want to have those rubber grommets on the mount or it'll drive you crazy with the noise humming thru the body metal
