That's your engine ground strap. Without it your engine gets it's ground
through the drivetrain and that can cause all sorts of sensor problems, rough
idle, etc. It goes back to the block. On the 93ZJ it uses the same bolt
that holds on the ignition coil, not sure about the 92 XJ.

Re: Headlights problem on XJ 1992
Holy crap!
Man you are some lucky, that ground strap is the main one for the body.
It controls the lights and the ignition computer.
Your body tub was stealing ground from somewhere else which can happen,
but normally when that strap goes, the engine dies and you have no
headlights. I have seen gear shifts and gas pedal cables be the
conductor... Also 2 way radios or stereos depending on their wiring.
That strap is supposed to go on the last head bolt, but if you have a
good connection on the manifold, just leave it.
That might be all the trouble.
