2021 OEM Alternator Type?

Read lot's of posts about alternators, but I can't seem to find an answer to what I hope is a simple question. For a 2021 Tundra, I'd like to know if the OEM alternator is a variable voltage ('smart' or computer controlled) alternator. My understanding it that the 'smart' variety require a a 'sensor' of some sort at the battery itself. Mine does NOT, so I'm assuming my alternator is of the standard variety. Thoughts? Thank you!

 

Did you ever determine if your Alternator was a smart' alternator? I have a 2021 Tundra as well and have been trying to figure this out too. Amazingly, all my internet searches have come up empty.

 

Hate reviving old threads, but at the same time this one shows up on Google and there's no definitive answer. I did some digging, and supposedly vehicles with a smart alternator have a sensor on the positive terminal of the battery. There is no sensor on the terminal of my 2021 Tundra. I feel fairly confident that the alternator is a standard old school alternator. An additional test I plan to perform is monitor voltage while driving. If it remains steady then the truck does not have a smart alternator. The volt gauge on the dash remains steady, but we all know those gauges might as well be idiot lights.

I also contacted Redarc as I'm installing a BCDC1225 in my Tundra. Have to say I was very impressed to get an email from their Australian tech support on a Sunday night. They weren't sure, but offered some ideas on how to wire for it if it is a smart alternator.
