I'm changing out the ECM in my 1987 YJ (2.5L, 4 cyl).
I've heard from people that there's often some discrepancy in the OEM part number for a given model/year/engine, but I don't know much more than that about the part numbering.
More to the point, I keep seeing these part numbers: 53005023, 8953002857, and 8953002099.
Does anyone know the difference between these parts? Or does anyone know the specific part number I should be looking for?
Many thanks for any advice.
