Default New AW4?

1997 XJ 4.0L I'm shopping for a new AW4 (due to my own F-up) and found one on Amazon, but they list it for only 1994-1996. Why those specific years? I thought the XJ AW4 was only changed in 1991 to the 23 spline output then it was the same until 2001.

Anybody confirm this? Is it a different TCU?

Part# S-4810179 keeps coming up for the '91 and later AW4's.

Looked at Jasper first and in the end it's the same price. I also would like to keep the old one for poops and giggles.
