That appears to indeed be a NipponDenso TOYOTA Alternator , its a Straight
Tab style ..........
you can take the WORLD CLASS part # 14540 and run it online to see whats
what with all that .............
it is very common place for aftermarket 3rd party re-builders to install wrong
pulleys , or sell a Angled TAB instead of a straight tab as u have there ......
one last observation , and moderate RED FLAG , your 2 smaller wires that
enter the unit below the large white one with a blue tracer stripe ,
are not secured with a factory Electrical Connector like the one i will show below ,
you should address this very sooner rather then later .............fyi
