Late build 02-03 matched PCM, SKIM, key and ignition cyl from a running driving 03 WJ 4.0. I used it on my early 02 and it works mint as long as you use the later style oil pressure sending unit. Will not work on 04, the trans programming is different and will not command the torque converter to lockup, but it will shift it normally and run the engine. This is great if you're having the orange "NO KEY" symbol on your dash accompanied by starting for 4 seconds and shutting off. $175obo Sold as-is.
