Need help identifying mystery wire

[randomfire]

[Edit] After looking at the manual, I'm pretty sure it's the ground wires for the coils. The end with the square hole clips to the O2 sensor connector housing, but I can't find where the other end screws into. Anyone have an idea?

I was getting ready to replace the spark plugs when I noticed this mystery wire not connected to anything. It's part of the ignition coil harness and for the life of me, I can't see what it's suppose to connect to. Looks to be the negative or grounding wire. Anyone know where it's suppose to go? Help!

Yes, coils grounds, attached to the back of the bloc with the o2 sensor connector

QFT. Back of cyl. head, under the engine lift mount hole. uses a 10mm bolt. I know because I have to bend it down to hoist the engine when doing transmission swaps . . .

This is where I ended up mounting the bracket. Back corner (driver side) of cyl. head?? The 10mm bolt there was barely in. I was able to unscrew it by hand. Whoever serviced my car last didn't bother putting the bracket back on or tightening the screw. How my car has been running this whole time is beyond me. I guess the ground wires aren't really necessary for the plugs to function???????

I know because my ground bolt break flush to the engine bloc. I fix the ground and the bracket in this engine lift hole with a big bolt.

It seems that you bracket is not at the proper place.

Hmm, can you elaborate a bit more where it's suppose to go then. That's the only place where all the wires (O2 sensor and coil harness) will reach with the bracket plugged into the O2 sensor connector housing.
