Take off the tail light and see where the wires go. One thing is for sure with it being exposed like that you asking for some sore of a short (and if unprotected by a fuse, possibly a fire) down the road.

 

Could it be a lojack setup from the previous owner??

 

Flux capacitor?

 

Yup, he's 100% right! Why didn't I see that? Oh well, there now you have it, it's the Flux Capacitor, case solved!

 

thats it, but it looks like a mkII flux capacitor.

 

Might I make a different analogy....
It could be an amplifier or sine wave regulator.
Do you have a kicker in the rear of the Jeep?

If not, then ignore my suggestion.
But if You do, then this might be a circuit to
help keep the sound distortion free.

Just my 2 cts.

 

Sorry but I don't understand ...what is Flux Capacitor??

 

Requires approx 1.21 gigawatts

 

"If my calculations are correct, when this baby hits eighty-eight miles per hour... you're gonna see some serious sh!t."

 

ok I understand now!...I have to buy a generator for the 1.21 Gigawatt.....
