Rain x does work great when going track speeds but when it's pouring and you are under yellow (12 hour endurance race) you need a wiper, what I did find out is there are three wires coming out of motor as opposed to the wires coming out of the relay and the case has a ground. One of the wires is fed by the stop ( self park) so I believe the other two are the high and low. Both have continuity to ground and one has more resistance so I'm thinking that's the low speed, il know tomorrow morning when we test on a battery .
