I am planning to swap a GM tilt, auto column shift column into my 73 Scout II. One big hurdle I have finally concurred is the wiper switch. I have spent Many evenings searching for info on wiring the GM wiper switch to a non-GM motor. IH forums, Jeep forums, hot-rodding forums, every type of GM style vehicle forum you can think of. it would seem pretty easy at first glance, but not all wiper motors and switches are created equal. I did lots of searching and inquiring and never found a definitive answer on how to make this work with a Scout II wiper motor. But i finally got it to work. This is a hot mess of relays and wires, but it works. While i do not yet have the column mounted in my rig, I was able to test the wiper switch and my relay contraption successfully. Park, low, High and washer all work from the stalk. Alas, the delay function does not. I have the delay box from the donor GM truck but this still eludes me. Feel free to use this info at your own risk. better yet, study it and figure out how i can simply this assortment of components that rivals the 1950's time circuit repair strapped to the hood of the DeLoren in Back to the Future part III. Some of the invaluable info i learned in my research: Scout II wiper motor uses one hot wire to "run" the motor (high), and a second hot wire to "limit" the motor speed for low. Ive lost track of the reference post on this forum with that info. GM column switch and GM motor original design does not send power to motor as the Scout II switch does, The GM switch provides varied paths from the hot wires coming from the motor through the switch and to ground. The Scout II switch has a hot wire connected that sends 12V+ to different legs of the motor in certain positions, with the ground taking place through the wiper motor to chassis ground not all GM column multifunction switches are created equal. Low setting on one switch might provide a ground path between a certain pair of wires on one switch, and different pair on another. This was what was most frustrating, as i had several circuits that should have worked according to switch diagrams. I finally just used my multimeter to find continuity to ground at different switch positions. I realize that in my picture, i have pin 85 and pin 86 labeling swapped on my relays. but you get the idea. it doesn't matter the direction on the relay, unless your relay has a diode b/t those pins. If you are not sure exactly how relays work and the different types available, (like me, at first), i encourage you to go to www.the12volt.com and spend time checking it out. It will be several weeks before i attempt the actual column swap, but this is on major hurdle out of the way. Ill post up pics and progress reports.
