New Guy Hello / 1992 Suzuki Sidekick Multiple Issues / What to Tackle First?

How do I tell if one of these spares is the right ECU or not. Maybe I can at least save the core charge on it.

I read: California, but doesn't match B61 or B64 to any of the ones on the list. Maybe not a Suzuki ECU? They both have a Mitsubishi logo on them.
