The pump is wired with the windshield wiper motor They use the same wire loom. If you are talking about an external aftermarket pump here is a post by member "Linus6129":

Ok, all done. Don't touch the wires at the switch, don't need to. Unplug the 2wire harness at the washer pump, unpin the terminals from the plug. There is a yellow wire and a blue wire. Mount your pump where you need it. I mounted mine on the fender well by the reservoir. Now get some wiring and wire up everything. My Trico pump came with black and white wiring so I ran the same colors back inside the cab to the original 2 wire harness. I put the white to yellow and the black to the blue wire. Turn on the power, tested, everything works the way it is suppose to. DONE.

The original wiring is shown in this thread.

The stock pump and after market pumps I have done are 12 volts to pump motor and the ground goes to the switch. So when you turn it on you ground it.

Positive is the Yellow wire and it comes from the fuse block to the washer pump then on to the wiper connector. Here is a picture of the wire connections on the wiper/pump. The Brown connector is the washer pump and the Black connectors are for the wiper. The Light Blue, Dark Blue, and Black wires go to the wiper switch in the dash.
