I was not the one who disconnected it, so am unsure. As you know the battery can be accessed from the back seat. It seems quite obvious to simply put the cord in the pic back into the terminal shown but I'm nervous to do something wrong...and the sparks that flew when I touched it to the terminal didn't help! Thanks for any advice.
Yep, you connect the terminal clamp to the tapered lug on top of the battery. It will spark a tiny bit due to the load of the dome lights because the door is open. There is also a very small draw from some of the electronics. Either way, that spark is normal and not dangerous as long as you aren't near a gas leak. Once the clamp is around the post, try to tap it down deeper with the plastic end of a screwdriver or a bit of wood. The lug is wider at the bottom and you want the clamp to get a good bite. After the clamp is well seated, tighten the nut to secure it. Test by trying to remove the clamp with your hand- you should not be able to move it at all.
