Locating Fan switches

I have a 1988 190e 2.3 and am trying to lacate the mechanical fan switch and electrical fan switch.

on my car they are located on the front of the engine near the thermostat. One is in front of the other, one has three wires and two prongs, the other has two wires and two prongs. Because each has two prongs, they could be interchanged, the plugs are identical.

I shorted each one, one starts the mechanical fan driven buy the belt, the other starts the 2 stage electrical cooling fan in the of the radiator and ac coil.

I want to make sure that these are plugged into the right sockets.

Is the switch in front supposed to contol the electrical fan and the one in back supposed to control the mechanical fan or is it vice versa?
