1979 wiper problems

[nomocrap]

I installed a new wiper motor and new switch original wiring is missing. My questions are [1] the motor has a black wire out of the case, a pink wire out of black plastic cover, 3 spades out of a plastic receptacle from the wiring the wires would be purple, white and grey. where do these go or hook up to? [2] how is the wiper switch wired and what colors go where. I don't have the parts to hook up the intermittent. Thanx for any HELP JAY

How much of the wiring harness is missing? There should be two large connectors that go through you firewall on the drivers side of our brake booster (when they're both plugged in it can look like 1)

Wiper motor
black connects to ground.
White connects to 12v and one side of your washer pump.
pink connects to the other side of your washer pump and goes through the firewall connector to your switch
Purple and grey also go though the firewall connector to your switch.

switch I'm not 100% on the positions of the connectors for these, and depending on how much wiring is missing these wires may not be there anymore,
black wire is ground. (This will connect to all other wires depending on switch position)
Light blue wire is 12v from instrument panel lighting
Pink is washer switch (will be connected to ground when switch is in wash position)
purple is speed control (connected to ground in high and low speed position)
grey is speed control (connected to ground in off and low speed position)

Hope that makes sense
wiring diagram is below
