1969 a-body wiper motor

I think I figured it out. My 1973 service manual actually has the schematics for 2 and 3 speed motors.

The park circuit is inoperative on my two speed wiper motor.

The resistor is supposed to be in series with the low speed.

Using some jumpers, I found that of the 4 spade connectors, the two closest to the motor can, the upper one is slow, the lower one is fast. (and that is without connecting the resistor)

The motor assy is internally grounded, so supplying 12 VDC to those two spades operates the motor.

that led me to believe the other two spades have to do with the park circuit. But applying power and ground in different combos produce nothing.

I could just run a single wire from the fast spade to an unused toggle switch on my accessory panel, and have non-parking fast wipers, enough to get through inspection.

What kind of moron is going to drive a hemi with slicks and a spool rear end in the rain anyway?
