from post #4:
What does the circuit look like if there is just a resistor between 85 and 86. There is about 100 ohms when I measure across 85 and 86 in either direction.Putting KISS's description into picture form :-

Note that a Bosch relay may include a diode across the relay coil, so polarity of the coil is important. The internet has conflicting views as to whether pin 85 or pin 86 should be grounded. Pin 86 should go to ground (as I show in the above pic) if the diode anode is connected to pin 86. Check the resistance between pins 85 and 86 to determine the diode polarity.
If the diode anode is connected to pin 85 then the wiring would be like this :-

This item refers to the possible diode presence.
If your actuator moves the wrong way when a pedal is pressed, just reverse the two connections to the actuator.
