It's a coolant temp sensor that keeps the EATC from coming on until the temp is at a certain level. The pigtail is very similar to the one that goes to the steering rack. Make sure you didn't plug it in to the wrong sensor.

The official name from Ford is the CELO (Cold Engine Lock Out) switch. Mine is non functional, as the heater comes on immediately even on the coldest Colorado days. Of course it blows ice cold air for the first 3-4 miles... I have been unable to find a new one. Anyone know where I can get a new one?

SHO Source may have a used CELO switch.
this one?

ECU Temperature Sensor (89-95)
This is the temperature sensor used by the engine computer (the gauge in the dash uses a different sensor). This sensor is critical to proper engine performance. If the computer thinks the engine is cold, it will run overly rich with reduced power and fuel mileage. Usually, but not always, a...

I'm pretty sure it only came as part of the pipe. Look online for a replacement pipe and it will come with the sensor.

No. That one goes into the coolant housing attached to the rear cylinder head. It tells the PCM when to turn the fan on.this one?

Nope. CELO switch not the ECU sender. They are located in different pipes but are within a few inches of each other.this one?

Thanks for the tip. I never looked for it as an assembly. What might the pipe/assembly be called?

Don't know if the CELO switch only came with the pipe itself. I personally doubt it but may be wrong. Would be called something like inlet tube w/ cyl. head tab to heater core.

Thanks. So far came up empty at rearcounter.com, Green Sales Company, and eBay. I'll keep looking.

Yeah the old reliable stuff is not coming up with anything.
Doug at FPS used to grab parts and stock them when chain supply was low (seals, crank sensors, etc) but this was not on the frequently repaired list for SHO's back in the day. You can always call or email FPS and ask.
It really looks like used is going to have to do unless you get really lucky.

I will second that you should email SHO Source. He has some used parts not listed on the web pages. He was able to hook me up with a replacement center timing belt cover from parts he had.
