Help.. Wiper Motor wire diagram

[COoverwatch]

hi all,
I am in the home stretch of wiring up a 66 GMC and can't figure out the windshield wiper setup. Previous shop cut, yanked, pulled all the old wiring out as the owner was going to put in a new harness. needles to say I got the job of finishing it up.

the motor is a Delco Remy 12-volt Type E motor as stamped on the end, original part number 5045500. this has 3 connections together and one off by it self. pump has two wires still attached, blue and yellow. yellow has a connector on the end, blue doesn't. switch has four connection on the back. L, H, P and with I think is power in??

If anyone could help me out I would really appreciate it so I can move this project to the done column.
