It's part number ts-158 at carquest. It has the same threads as the temp sending unit(although i'm putting mine in the intake, just wanted to use a reference). It's normally open, and closes at 185, then opens back up at 195-200. It fits 88-92 fords i believe. The downside is its a two wire switch. So you have an extra wire in the harness. Maybe this will help someone else out down the road.
Found a fan switch I like...

Did you actually mean switch normally open, closes at 195-200, opens at 185?
Sounds like you want a switch compatible with a 180 thermostat? And you would prefer a one-wire switch? You might like the FS-113 from Napa even better. Similar basic thermal parameters, 3/8" pipe thread, single wire grounding switch.
Note that if you ask, possibly persistently, Napa has a book with pictures and operating parameters of all of their fan switches. There are at least 3 different GM style switches in the book with different on/off temperature points. You can also find some cross reference info with alternate source part numbers (like GMs).
I strongly suspect all/most of these switches are made by the same company anyways. I have seen a lot of 'made in Brazil' on fan switches it seems.

sorry if i wasn't clear. i meant it closes the connection, completing the circuit, at 185, and opens, breaking the circuit, at 195-200. I do like the fs-113, but we dont have a napa anymore, and this i found at carquest. They too have a bood, but no fs-113, or ts-113. This is just what i found here, local milage may vary.
FYI, they came on 88-92 tempos for sure, thats what i snagged the connector off of.

Umm... that does not make sense. Why would you want a fan switch that opens at higher temperatures? Sounds like it was meant to be a binary temperature sensor rather than a fan switch.ellis569 said:

Thought so 
You might also want to cross reference a 203-degree GM thermostatic switch p/n 3053190. This is the GM # for the Napa FS-113 if I remember correctly. Supposedly used in Grand Nationals.
