I have a set of old Mercedes power car seats. The seats are are normally controlled via door-mounted switches using a CAN bus. I want to control the motors directly. They can be easily powered forward/backward by wiring directly and changing the polarity.
The seats also have separate switches embedded into the seat (not the door). These switches are supposed to control a seat massage function, but I want to re-use them to control the seat position motors.
When I test the switches with a continuity tester, I can see there is a unique change in impedance (Confirmed with multimeter).
Question: what is the easiest way to use those switches to control the seat position? Ideally something that could interpret the ohm level and differentially trigger a relay(s) controlling a motor. Is that possible? I’d like to avoid anything like an Arduino setup.
