Scangauge

I used a Scangauge very effectively with my Gen 3 Prius. Does anybody know if the OBD2 codes for the Gen 4 are the same?

Also where is the ODB2 port?

I have a list (somewhere) of the codes for tweaking things on the Gen 3 - eg turn off reversing beeps. Is there a similar list for the Gen 4 - eg for linking window control to lock/unlock?

I moved my ScanGauge from a Gen3 to a Gen4 back in 2016 and can confirm all the Gauges I used did work. They were from a spreadsheet posted ages ago on PriusChat. 
 

I also changed the reverse beep to a single beep myself, but can’t recall if I used the ScanGauge for that. I did for the Gen3, but for the Gen4 I may have used the Carista device and its app. Carista did offer a wider range of DIY custom modifications than ScanGauge at that time. 
 

Apologies that my knowledge is not more up to date. 

The port is under the steering wheel; within a metre of it, as it should always be.
