GM Stalk wiper questions

[vintovka]

Have a 87 C-10 chevy van column installed and would like to use the stalk lever to control the new aftermarket windshield wiper and add on washer work. The lever works fine for high beam control and the new wiper motor operates fine off the dash mounted switch that came with it. Is there a wiring diagram (for dummies) to show how to make these connections? I googled everything and cam up empty already. Was thinking if i could identify the factory leads I could cut into the 3 position dash switch and have wither one function. I do have the delay module out of the original 84 K10 and would like to make it it work as well. Thanks for any help.
