A mechanic friend of mine lent me one of his catalogs to flip through and I found this fan switch for a mid-80s Mercedes 190E.
According to the data sheet, one circuit closes at 212F, and the other closes at 224F. This would be good for the Taurus fans since it would be in between the stock electric fan; the low speed Taurus fan would kick on at 212, the ECM would kick on the stock fan at ~217, and the high speed Taurus fan would kick on at 224. Perfect.
Some problems...
First, the only place I can find this is on NAPA and none of the other vendors have a three-pin fan switch. I originally found it in a BWD-Niehoff catalog but Advance Auto doesn't even show any matches for the part (TFS611). My guess is that nobody makes this anymore, so it's not going to be a long-term solution.
I have no idea on where to try and find a pigtail. Maybe there are MB junkyards that would have it. Maybe some of the pigtail parts makers still produce one. I haven't even started looking.
I don't know the pin-out or the switch behavior (does circuit 1 close when circuit 2 opens? dunno).
The thread is 14mm, so you will need to find a way to put a 14mm bung onto something.
