first, no TJ doors ain't gonna work on YJ. latches are different.
second: don't know it may or may not have it.
third, if it DOES have AC you can gut the AC system and run it a tank. i just finished mine, its slick.
if you don't have OBA, ya gotta fiddle with brackets and crap off an XJ to make it work. thats how mine is setup. i couldn't tell ya what came off what though.
if you have AC, you can come take a look at my setup anytime
