Ok so my friend has a 96 jeep cherokee and wants to know wtf something is. It is behind the front bumper on the passenger side and is bolted to the bumper right by the horn. It looks like a pill, its about a 10" long cylinder about 3.5" in diameter made of black plastic. A wire runs from it to something in the engine bay on the front passenger side, and from there a cable runs to the throtle. And he commisioned me to find out what it is so I come to you guys. Any ideas?

No Monty anymore!
Looking for a 95 SR in good shape, so keep an eye out!
