Best battery that would just bolt on...

Huh? Maybe we need to talk about the definition of "grounded". To me, the grounded line is the one attached to the chassis, on the 993 it's clearly the one that is a bare copper braided line, and is the one that is farthest away from the front of the car, and attaches to the -ve of the battery. The nearer line to the front of the car, with a rubber sleeve covering the conductor, is connected to the +ve, and is the "live" wire.

And it is the mtp-48. A tiny bit bigger and higher capacity but others reported success with them in my search on this board.

One the +ve side, I now have a permanent engineers ring (in scar tissue!)

Also, since I now know the second wire connected to the positive terminal is not the ground, what is it?

Wearing latex gloves is like wearing a condom...good protection but not foolproof.
The problem with wearing a ring or jewelry around electrical apparatus is that, if you get it between the + and a ground, you get all the "juice" through that metal, hence burning flesh and the possibility of actually burning your finger off.
I believe the smaller wire coming off the + battery terminal is the feed to the fuse/distribution panel. The larger cable goes to the starter.

Was using a 13mm wrench to tighten down the positive, and it slipped, my hand holding the wrench dropped, and the ring came in contact with the -Ve terminal, and we had a connection though the ring to the wrench as I gripped it to the other end of the ring which was contacted to the +Ve.
Long story:
Lead acid batteries are good for very short high amp discharges, so the ring immediately went RED/White - it looked like THE Ring in Lord of the Rings. I dropped the wrench, and ran out to the house to do a cold water rinse, yelling curse words all the way - oh it was around midnight, and my kids locked the house up! Ok, fumbled with the keys, got in, and run cold water on it - my wife woke up from all the cursing, and came down.
Ok, big problem - the ring has not been off my finger since I graduated as an EE in '83, and now it had burned its way into my skin. I figured by the time I got to the hospital, the finger would have swollen and I would likely lose the finger, so I had to get it off. I tried to twist if off, and weirdly first tried to see if my finger was still attached strong enough so I would not twist if off as well. It was good, so I twisted, no go, so we poured soap on it and twisted - and pop the ring came off - and now I had an open deep burn wound all the way around my finger, soap everywhere, and it hurts like hell ....
So I did what any other Porsche fiend would do - did I mention that I was preparing for a show the next day? - I wrapped it all up, went down to the shop, and continues to install the battery. Go it finished!!
I went to the clinic next day, it was pretty messy. Bad burns, a bit of bone exposed, limited circulation in the finger. However, they did some cleanup (ouch!), and with silver cremes and other bandages (including ones that were not supposed to bind to the wounds but were actually soaked in super-glue and every removal causes you to start all over), wrappings I made it though the summer and by fall it was back to normal. Lost a whole swimming season, and no sympathy from the wife, since I was working on the "Porsche", not the house...
Is nicely healed now, but with a nice ring of scar tissue that looks like a ring. Now when I meet other engineers, i can say that I have a "real" engineers ring. Picture is crappy, you can see the raised edge of the ring burn...it healed really clean and it goes all the way around.
Cheers,
Mike

Tip from an old, retired jeweler (me): If you need to get a ring off your finger, either due to an accident, swelling or just too tight, place your hand in or under cold water to reduce swelling, then spray on WINDEX. Ring should slide right off. If not, you'll need to go to a jeweler with special ring-cutting pliers. If you go to an emergency room, they will probably ruin the ring.
