Control unit, electronic ist 34750-zx2-000ah

[Bmbf225]

Wondered what is actually function/purpose of this control unit 34750-ZX2-000AH? (#13 in ELECTRICAL PARTS BOX -MOTOR CONTROL illustration at https://peparts.honda.com/marine#/browse/me/bf/bf225/BF225A2-LA). My 2003 BF225A has serial BAGJ-1003xxx and according to illustration there's such high priced box, but have found no information of its purpose at all.

Just a guess but it may have something to do with hooking up multiple outboards. It does have an associated cable assembly listed. See item 2 in link below:

I found a reference online for 2017 models that indicated iST stands for
"Intelligent Shifting and Throttle" and that was about multiple outboard control.

Again, just guessing (and geeking out ;>)
