Pretty sure AC is the last of the short coding 2wd drive pumps.
Pretty sure AB is the last of the short coding 4wd drive pumps.
BD alphabetically is later than ones above so with long coding & different wiring
When you find one, if different revision, you'll then need to check if it came off a 2wd or 4wd car as they aren't compatible.
To be fair, unless you want to research, best just look for the same as you have!
Will still need coding, but that's the easy part.
