Here's a few photos that might help.
Note on the bare motor photo the recess and slit in the front of plastic slide.
If no coordinator, the cable goes in the front casting housing recess and cable end and washer goes to bottom of slit. Screw holds cable in tightly and only the knob works the slide. End of cable pushes against slide and washer caught by the cable end crimp against the slit pulls it back.
Note the end of coordinator -- cable and washer similar to switch cable end and the flat extension with a slot off to the side of block.
Coordinator now goes in the front and it's cable end and washer is installed in the recess and slit the same way as the regular switch cable would have been. The block extension with the slot is positioned so slot is adjacent to the rear cable housing recess in motor casting.
Switch cable is now in the rear casting recess. Make sure it goes thru the small slot in extension at end of coordinator block. The washer and end of cable are between the slide and the slot on the coordinator block. It is not directly attached to either. Once in position, turn the knob to pull the coordinator slot and cable housing together while still keeping cable housing in the casting recess. Tighten the screw and washer onto cable.
Operation with coordinator:
When knob is turned to extend the cable, cable end pushes against the slide which moves and pulls the coordinator along with it.
When turning off by the knob, the cable end being crimped holds the washer which then bears against the slot on coordinator block and pulls it back. Since it is attached to the slide, that also is pulled back.
When windshield washer is in operation, the coordinator does it all. Since the cable from switch is not directly connected to slide, it does not interfere or come into play. The piston in coordinator extends and moves the slide. The air bleed slowly allows the spring to return the piston home when vacuum is cut off and thus pulls the slide back with it.
If the knob was turned after the coordinator was extended and switch cable was then preventing the slide from coming back, the coordinator just slides toward motor as it would normally do with switch operation as it tries to return it's piston to rest position. The knob would then turn everything off as usual when operator desired.
