Wiper wiring 3-speed '74 dart sport ?

mymopar.com has downloadable wiring diagrams, though that isn’t going to help you with bare wires.
On my 68 (might not be the same, yet a good chance) red, brown, & green from terminals E,F, G, connect directly to motor, blue (H) goes through the “park” switch under the motor cover.
Drawing is switch, through the firewall, to the motor.
