What is the ecu number you guys used or did you have good luck at a junkyard. At the parts store it doesnt show a list for a manual 4wd. Just 4 automatic 4wd numbers. If any of you guys have a stock 4.0 5spd 4wd id appreciate it if you could give me the numbers.

Thx a lot. Ill check out the links on lunch brake. n i agree about the 4wd bit. Switch to control module in the extd cab portion to tcase motor
 
im running one from a 91-92 explorer 4.0, 5sp. code is x2x2. supposedly they are programmed to have a little stronger low end since the explorer had more weight over the rear. i put it in when i did my 4.0 swap so i dont have a comparison, but it runs my 4.0 just fine.
 
I found a chilton manual. Figurrd out why my 93 ecu wont run my truck worth shit. They changed pins around and added egr, 2 o2 sensors, and cam sensor. 91-92 pins r the same.
