Welcome!

The 3 terminals that are grouped together are for the wiper motor. The other 2 terminals are for the washer pump solenoid.

On the group of 3 terminals for the motor, one of them should be spaced a bit farther away from the other 2. That one is the "low" speed terminal. The middle terminal is the "high" speed terminal. And the remaining terminal is the power terminal.

Your new harness should have a wiper power feed wire that will get connected directly to the motor's power feed terminal. Then there will be 2 wires that run directly from the motor's "low" and "high" terminals to the corresponding "low" and "high" terminals on the dash switch. The switch completes the circuit to ground to operate the motor so the body of the switch needs to be grounded by mounting it in the metal dash.

To hook up the washer pump, you'll need a short jumper wire running between the wiper motor's power feed terminal and one of the 2 pump solenoid terminals. Then the other pump solenoid terminal gets connected to the "wash" terminal on the dash switch. Note that the polarity of the 2 washer solenoid terminals doesn't matter (just supply power to one of them and ground the other). The pump is mechanically driven off the wiper motor and the solenoid simply engages the drive mechanism. So the motor also has to be running to make the pump function.

Finally, the wiper motor assembly should have a copper/brass ground strap that bridges across one of the rubber mounting grommets. That ground is used by the parking switch inside the motor gearbox assembly. It allows the motor to continue running until it reaches the parked position if the dash switch is turned off mid-wipe. The motor will still run if this ground is bad/missing but the parking feature won't be functional.
