Anyone know where to get one? Have the wiring diagram for the computer but need the chart with pin descriptions. TIA.
 
I have a bunch of TJ FSM's...and then have this one labeled '84-'91 (for some reason, I think it's for a Cherokee, but it doesn't say)...

any chance yours looks somewhat like this?

Sorry I didn't clarify, its for a '92 Cherokee 4.0l. Motor is going in the yj. The '92 is a HO motor...would that chart work for the '92 computer? If not, do you have one for a '92?

that's the only one I have that's not for a TJ...

the TJ ones have 3 connectors...that diagram looks like it just has 2...

do the colors match yours? if so, it's probably the same...if not, I'm of no further help...:)
