The connectors for them should be dangling there somewhere? Why would parts of the harness be missing?

The motor gets 12v at all times, then the switch grounds out either high, low, or the washer pump. It should be easy to locate a diagram to help you out, most any mid 70's GM vehicle has the same wiper electrical and pigtails. I'd highly recommend getting pigtails from a donor vehicle and wire those in, rather than individual connectors to each pin. Dash fires suck.

will look for some pig tails then and maybe I'll see how they're hooked up too. had power to center one and grounded each side and both and nothing. assume motor housings grounded on firewall so not sure if it's bad. not sure to test. can figure the switch out if I can get motor working
