Aux Fan Temp switch

I dont think my aux fans for the 90 300d are turning on like they are supposed too. When coolant temp hits 105 or so, the fan doesnt turn on. When i touch the 2 wires together that go to the switch, the fans turn on and stay on till temp goes down.
The temp switch was replaced a couple months ago. The 2 wires that go to the switch lost their holder. Does it matter which of the wires goes to which post?
