Hi folks! Gotta quick question. What is this and what does it do? It's connected to the intake manifold, has two wires coming out the top of it (both of which need repair), and sits in front of the ignition coil. That hose veering off to the left goes to the firewall/heater core. Any ideas??
the sensor that sends the temp to the gauges is on the driver side in the front of the lower intake manifold, there is a single wire pushed onto the sensor.

Looks like the Engine Coolant Temperature (ECT) sensor....'85 LX?....CFI or an EFI transplant?

Coolant temperature sensor, not the temp sending unit for the gauge.

Joel, I see where you're going with that question. No, it's carbed. You're thinking that this sensor is reporting info back to a computer (no computer on pre-86's, correct??). So to what is it reporting the temp info to??
There's a computer, it just doesn't operate or control the engine.

That's weird, my '84 (4V HO) didn't have that. It's possible that someone swapped that heater hose bung on there, but why would they route the wires?
Unless its for an electric fan someone put on there...

Hard to say Meangreen. No electric fan. Are connectors like this easy to find/replace? The wires are essentially ripped from it and will have to be repaired somehow.
First, there were "computers" before '86....'84 and '85 5.0L Mustangs/Capris that were ordered with an automatic transmission (AOD) got EFI (CFI, Ford's version of TBI). It is not the same thing as '86-'95 SEFI.
Second, even the '85 carbureted 5.0L model got a computer. It was supposed to be for a "two speed accessory drive" (TSAD) system that pre-production models got but it never made it into actual production use.
So the question is...was your '85 originally CFI/AOD w/ EEC-IV or was it originally carb/T-5 and got the TSAD computer? If you aren't the original owner, how do you know what is and isn't original? A quick look at the Vehicle Certification Label ("door sticker") and Body/Buck Tag will confirm what the car was originally. The VIN will not tell you as both carbureted and fuel-injected models had the same engine code (M).
People have removed those TSAD computers when they purge their cars of all emissions controls and then had trouble with their AC working.
