hi guys and girls. i need help with wiring the 2 speed switch to the wiper motor. my wiper switch harness has 3 wires , a grnd , 1 dark blue and 1 light blue. i tried searches, but no help. the wiper motor has 3 spades for the wiper sw hookup plus 2 spades for the washer pump. i changed the fuse panel from glass fuses to spades. i attached a blue wire marked wiper motor power to the middle spade from fuse panel on the 3 spade location. i have power to that spade after checking with the tester light. where do the other 2 go? the wiper sw is a 1994151 standard 2 sp sw. thanks in advance for any help.
