Mystery Ground

Could anyone help identify where this ground goes? It's on the main ground harness with the negative starter connections and ground to Driver side strut.
I've ran w/ it disconnected and everything's fine but I connected it on the starter and gave me hesitation and bucking problems... HELP!

There is another ground, besides the strut tower ground, that attaches to one of the bell housing bolts. So if the wire will reach the rear of the engine, it most likely is the one that attaches there.

thats a main battery connection. there are two, power and ground. they both run to near the starter. one from the battery positive to the back of the starter on the solenoid. the other to the engine side of the upper most starter mounting bolt (nut side). dont mix the two up. look near your battery to verify which wire (pos or neg) is marked with the stripe, or better yet test for continunity between the battery terminals (with the battery disconnected) and those terminals.

It has a black w/ yellow stripe so I assume ground. Yes, I think it does reach the rear of the engine block... should I attach it there?

It's not for the starter.

NEVER ASSUME THAT.
There's a LOT of black wires that turn out to be powered.

The starter does NOT have a "ground wire".
All wires going to the starter are POWERED.
If you try and ground any of those wires, you're going to end up blowing fuses and / or causing an electrical fire.
The starter grounds through it's casing into the engine block.

If you don't know what a wire does, that's what the FSM is for.

pretty sure that wire is held by one of the bell housing bolts.

Thanx Ted for correcting me... but I did look at the FSM and I just can't find it. I looked under Engine and body electrical...
And wouldnt' the bell housing bolts be that same as the engine block?
