So I have a gen4 3s in my st165 and I'm trying to get my tach to work. Since the motor uses an ecu based tach I need to change or bypass the resistor but I'm not sure on which resistor it might be since the circuit board looks different than in the sw20 so I can't use it as a comparison My guess is this one in the picture but can anyone clarify? Or maybe one in the other picture?
