Default 98 C5 Harness Ground Wires

Need some help on where these wires attach.

I’ve reviewed many posts regarding grounds but they touch on locations, cleanliness, and what’s in them, it seems.

I just don’t know where to attach these cables. Is it as simple as any ground? Or specific ones?

There are 3 on the passenger side and 1 on the driver side.

Driver side wire before injectors.

Passenger side before injectors near starter.

There are some ground wires that attach at the back of the cylinder heads, could be them?

I appreciate the info, I am looking for a bit more detail than that.

I have found alot of good info just with the searching here but still perplexed. I feel like I have some stuff backwards even on the drivers side. I think ive got the main ground from drivers side frame rail backwards, its currently into the cylinder head, but seems backwards as I want a steel ground I assume. And then probably put the small black wire onto the cylinder head. Also, on the passenger side, I've got the thick black going to cylinder head but again, want steel, so that must go to the block I think, and then the random black with stripe onto cylinder head as it does on drivers side.
