Anyone know the proper wiring for a bench test of my 79 wiper motor?

Thank you.
I do have the wiring diagram, however I am trying to sort out various things after a hard life as a race car.  I have some really odd combinations of options  IE. factory security system without power locks etc.  The harness is not all cut up and such, but isolating the wiper problem down to switch, wiring or motor has been an exercise in frustration.  I finally replaced the motor with a new unit figuring it was at the end of its service life anyway.  I do not need the delayed pulse system to operate on intermittant.  Only Low, High and Park.
Any thoughts? 
thanks

Is yours a round motor, or square motor? I can also send you the testing info as a PDF file. Also, does the car HAVE intermittent wipers? If so, there is a control "module" for them that can keep the wipers from working at all.

This was very helpful.  I have my wiring straightened out and the pulse delay bypassed.  However (though not electrical)  Is there information on replacing the bracket or the studs only that hold the wiper motor.  It appears that the bracket holding the studs is bonded to the fiberglass cowl.  It may just be sealant or something, but I do not want to hurt the body or bracket tearing it off.  Can just the studs(screws) just be removed or does the whole bracket come out as a unit.  If it comes out easily I will remove the rusted/unserviceable studs and replace them with stainless if possible to better resist the Louisiana weather.
thanks
