Need help with 65 wiper motor

[rsev216]

I am rewiring my 65 convertible with the Painless harness. I bought an after market 1 speed wiper motor that has unmarked orange, blue and black wires. Painless tells me which motor function to connect to which wire but no help as to which motor wire is which function. Can someone help with which motor wire in the Constant B+, which wire wire is Motor On and which wire is Park???? The old harness and motor were removed several months ago before the car went to the body shop so there is nothing to compare against.

I would really appreciate some help as I have spent the last 2 days trying to sort it out.

In a DC system (battery operated), black is typically ground.
