Thank you!

I have a 1988 MJ. Wanting to upgrade the ECU, I purchased an ECU # EF8953005428 to swap out for my old one. Just got the existing one out of my MJ and now I'm wondering if it might be from a newer-than-88 MJ. Wondering if anyone on here can confirm? Numbers from the existing one: 53007842 and S101155201A; also has a white sticker on the corner saying "9012". Picture of existing ECU attached. Thanks, Justin
