Can't find where these connectors should connect to on 74 240d (114)

I am trying to fix my AC on my 1974 240d (114). Last year my MB mechanic replaced the compressor, hoses, pretty much everything under the hood. I didn't replace the switch on my dash yet.

Yesterday I looked under the hood and found these two connectors not connected to anything. Before I take it to MB dealer, anybody have any idea where these should connect to (see image)?

Not to the electric fan, that's just after the thermostat (upper hose to the radiator at the engine side) and has one wire on it. Unplug it touch it to ground to test the electric fan.

Those two wires do look like they came off the dryer (the canister like device on the firewall that the AC hose passes through) on your photo it just out of the frame at about 10 o'clock.

I'll confirm the color codes on my car tonight ins post.
