Resolved 2G HELP! Can somebody please identify this engine electrical plug??

[Pyrolite]

I have a 1996 Eagle Talon TSi, its front-wheel drive turbo.

I've had this engine apart for several years rebuilding the entire thing, and I'm hooking everything back up to the block and head. But I don't remember anything about this plug, I have no clue what it is or where it goes.

It looks like just a really short bolt with a very large flange, with just one wire attached to the top of it. The bottom side and threads look very clean and the top side is rusted so I know it came out of somewhere. The wire is over a foot long and just goes into a bundle of other wires between the battery and the engine.

I don't know if its some kind of sensor or grounding wire, or if its meant to plug up something, but the wire is long enough that I can't tell if it goes to something on the front of the engine, or the back of it, or the side, or the bottom, or anything...

PLEASE HELP!

Thanks,
Brian

Its a Knock Sensor, it goes into the back of your block.

Thank you everyone!

Just wondering does it go into the hole that is right next to where the Intake Manifold Stay bolts to the block...

Or does it go into the hole below all that where you are supposed to shove a screwdriver into the block to make sure the balance shaft/oil pump is timed correctly?

The screw hole beside the Manifold Stay bottoms out, the other one is open to the inside of the engine.

Which one should it go in, and if it goes into the open hole, does anything else bolt into the closed hole?

The top. The open hole for the balance shaft check should have a bolt plugging it, part number MD065945 if you want the OEM one, but it's a M10 x 1.25mm pitch and should be no more than 20mm long. Some have recommended using a crush washer and thread sealant on it to prevent leaking.
