It's dark outside already (no garage for us, unfortunately), and I ain't been feeling good, but I poked around and all I got was this:

The black plastic sheathing is missing in a spot from a bunch of wires that actually terminate in two places.

One group of wires (sheathed at this point), terminates in a female black plug that attaches to a little aluminum-colored metal cylinder about 2" tall and 1" wide, directly in front of the battery. That black female plug has the numbers 011 5457128 on it.

The second group of wires (smaller bundle) in the sheathe plugs into another plug nearby. It has the numbers 012 545 0428 (or 6) stamped on it.

The whole shebang seems to enter the firewall without a plug, just stright through? Maybe? I really couldn't see well, as it was so dark. I'll have to get out there tomorrow and pull out the battery and rectify this info.

Thanks so much,
Jimmy
