Mystery Plug = What Is It?

[huntr1]

Changed the oil in my '97 K1500 suburban last night. When I went to do the filter, I saw a plug hanging down. I have no idea what it goes to. It's the orange plug on the gray wrapped wire in the attached picture. It hangs right below the oil filter, by the driveshaft and the front o2 sensor. Truck is running fine, but I would like to re-attatch the plug to whatever it is supposed to connect to. Any ideas?

Found it!

It's the connector for the block heater.

I think.

It's the Dilithium Crystal Polarizer.

It's where you plug in the BFDA (Blinker Fluid Diagnostic Analyzer)

Where is the other end connected to?

I've had lots of cars with block heaters. Connector always looked like this.

Thats the end that goes to the house...what he is looking at is the end that goes to the heater on the engine.

Correct. The end I posted a picture of is the end that plugs into the actual block heater in the block.
