Re: what the heck are all those wires for on my wiper motor/pump?
so,
I left the lowermost (3 wires) harness plugged in (wiper motor power)
Unlplugged the middle harness (2 wire) pump solenoid
and unplugged the upper harness (3 wire I think)
with the top harness unplugged the wipers won't return to the down position on their own when the switch is turned off.
that solves that mystery.
