No. The bolt patterns are different.
I don't know of a kill switch but there is a crank sensor.
That would depend on the condition on the jeep.

Yes, J.W.Speaker makes a set of LED headlights for the 1984-2001 Jeep Cherokee - called 8900. They are 5x7" and fit the Jeep Commanche MJ and the Jeep Wrangler YJ as well. They are even ECE approved, so they are road legal in Europe. Their technology is based on a product development for the Oskosh vehicle of the US army.
Last I heard, there was no such thing as radiator sealant in a commanche. If you have a hole, you need a new radiator. Try tightning down all the hoses first, though.
