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 goes through the “park” switch under the motor cover.
Drawing is switch, through the firewall, to the motor.

I believe the newer version is different, but colors in half of firewall connector ( 8 total ) are the same as yours - I hope to get a meter on it Sunday/Monday, run some tests , 1 of the switches I have matches your diagram I think ? ( were 2 in the car ) , what a crazy system, many versions ! Thx brother - I'll keep digging & posting
