W140 seat switch signals
There are 7 pins on the seat switch and 6 motors on the seat itself...
was wondering what the signals/pulses are FROM the switch to the seat control unit... is it a 1to1 for each motor? or is it a whole lot more complicated than that? :) |
That car uses a voltage drop (resistance value change) to control the seat computers.
|
it's not a direct +/- voltage to the motor then... would you know what voltage the microswitches can take? If I can somehow isolate them...apart from the PCB
