Mystery wires?

I was looking under the hood of '99 XJ Sport when I noticed two wires surrounded by a round flexible plastic shroud. The two wires come directly off the positive battery node. The shroud leads to the firewall where there are two "switches" with multiple wires connected to them, but each has an open, unused connector. It appears these two battery wires connect to these two switches. I bought my Jeep last year and there's no doubt these wires were disconnected by a previous owner. Does anyone have an idea as to what these two straight from the battery wires are for and why someone might disconnect them? Thanks!

Sounds aftermarket, maybe previous owner had a CB/sound system/winch??
Where about on the firewall? The firewall is a large area..
Pics are always helpful!

I'' try and take some pics. The wires are definitely not aftermarket as they are clearly designed to come out as part of the battery's positive node. The wires are actually a part of the positive cable itself beginning where the cable attached to the battery. The two connecting switches on the firewall are like two inches square and maybe six or eight inches apart. They have several other wires attached and they appear to be there from day one, not aftermarket either. I'm so tempted to plug the two "dead end" wires to the switches to see what happens but I'm afraid I'll fry something doing it. The length of the wires is only two feet at most and both have ends that fit right on the switches, one each.

How can you be so sure the battery cables are "Factory" cables and not aftermarket?

And wouldn't it be better to see where the wires on that "switch" go to before you find out the hard way WHY the PO kept it unplugged??

If i recall correctly. The positive battery cable goes 2 places. The alternator/fuse box and to the starter. That's it....

Sounds to me like a couple of circuit breakers, or relays, installed by either the PO, or by his mechanic or a stereo installer for some aftermarket accessory. Try testing the wires for juice...with a volt meter...not by touching them to each other.

Molded connectors can be had at ANY parts or electronics store giving it a "stock" appearance. Like said above, a picture says a thousand words. You might need to show us what you're describing.

I have an aftermarket circuit breaker and 4 extra relays for lights and other accessories. It does NOT look stock...but some guys, or their mechanics are very skilled at adding electronics and other modifications. Not me, but some guys. Mine works fine, not pretty,but functional.

Exactly, i have always seen wires go that way; they must be aftermarket. We could tell more from pics. Maybe you can use them for something.
