4.0 conversion ECM HELP

Hello, I am in the process of a 4.0 conversion on a 1990 4 banger wrangler. My engine and tranny donor are from a 1991 jeep wrangler rengade 4.0 5-speed. I was wondering if a ECM from a 1992 jeep wrangler 4.0 5-speed fed emission would work for my conversion??

Yes it will. Computers, wiring, and sensors are the same.
