This has been on my mind for sometime if it could be possible to operate a '84-'88 delay wiper motor with a '80-'81 dash mounted delay switch. I know the '83 & older has the power circuit going to the motor, ground to the switch. "84 & newer is reversed. The idea is to switch my '81's power to the switch like the newer one, send the ground to the motor. I'm not worried about the motor as much as the switch. As it just completes the power loop per each circuit (low, high, delay settings...) the electric flow shouldn't affect the function unlike a DC motor. Both switches have the 91, 92, 94 & 95 circuits which works with my idea. The 150 ground would be swapped with the 93 power. Same as for the wiper motor but the newer one has a circuit (196) that only connects between two terminals on the motor itself & needs 93 to be replaced by 150. Simple enough but then I have to figure if the delay selector (guessing its a rheostat) on the dash switch would perform like the column switch delay selector & have the same ohm value range. I wish I knew more about electric systems other than how to build harnesses & repair wires & terminals. So if any of you guys who really know anything about this let me know what you guys think & know.
