Default where does this electrical plug connect to? See pic

hey, just doing the electrical connections of my 99 LS1 after installing the engine back in. I came to THIS plug, and I can't seem to find where it plugs in... i pulled the motor 3 months ago, took a bunch of pictures, but i can't find this little tid bit of info...

the picture is taken on the passenger side, you can see the starter and the exhaust manifold in the picture. you can see that this wire comes out of the same place where the "oil level sensor" connector branches out of the harness.

this connector isn't long enough to get up to the top of the engine. I'm assuming it plugs in somewhere near the starter...

any help appreciated,
Thanks,
John

just a guess but would it be for one of your oxygen sensors?

It looks like directly to the left in the photo is where one of the O2 sensors plugs in. The other should be mounted right by it.

crank position sensor, above the starter.

O2 sensors are 4 wire flat and square, isn't either one of those.

knew it was something like that.... I felt around for a spot to plug it in above the starter, couldn't find one.... I'll have to feel around a little more.
