    Thanks, how does this differ from the Stec controller that is lower in the stack?

    I believe the one below is the main “head unit” of the AP. Do a search for the STEC manuals. Logbooks/STC should explain what was installed.

    ^^^ This.

    Your autopilot is an analogue Piper Autocontrol IIIB/Century IIB (just below your circled item). It's a single axis autopilot with heading control (Nav/LOC) through the HSI.

    As @Arrow76R noted, your circled item is an ST-360. It's an "add on" box that works with the Century IIB autopilot to provide altitude alerting/altitude hold and vertical speed.

    The Century IIB is still considered a pretty good autopilot and there's good support still available to keep them working properly.

    @GRG55 is correct, but to be completely pedantic the add-on capability comes from the S-Tec 60PSS (below the IIB), which adds the second axis of control (alt hold, VS and GS capability) The century IIB remains the lateral control system. The ST-360 then adds-on to the 60PSS to add alt preselect capability and better VS control.
