in all the write ups for a b16a swap into an 89 std hatch, it says to make sure there is a tranny ground. now when it had the d15 in there it had a wire from near the the clutch cable to the negative batt post, is this the ground wire that is being spoken of? or is there suppost to be a ground to the frame as well from the tranny? sort of confusing because they say this messes alot of people up. if it is the cable to the negative batt cable from the tranny, how can this mess u up seeing as you have to have a cable to the neg batt terminal, are people just forgetting they have 2 batt terminals?? or is it a separate ground??

Make it easy - go on Ebay, get a ground wire kit, and use it.
There are 8 wires, total -
1. Battery to Head
2. Battery to Block
3. Battery to Frame
4. Battery to etc.
5. Battery to etc.
6. Battery to etc.
7. Battery to etc.
8. Battery to etc.
Often times, those extras are used for accessories, but can be used on different parts of the engine assembly, or any way you see fit.
Replacing the grounds and ensuring proper contact is one of the best ways to gain 1 or 2 MPG and gain driveability. It also makes your alternator not have to work as hard, due to less resistance in the electrical system.
Clean/repair your grounds any time you see a problem with them. I always recommend replacing the OEM grounds with at least 8g wire and soldered lug ends. Use Amp wire... it comes in colors and looks cool.
