Anyone charge their 1995 or newer A/C

Like the title states:

1) Anyone charge their 1995 Hijet’s A/C?
2) Is it R-12 or R-134A?
3) Where are ports?

 

on my 2021 Hijet truck 3BD-S500P the ports are under driver seat in engine bay, just lift the seat and you can see it. Differences between R12 and R134a you can see immy, as the connection ports are different , R134a https://diyparts.com/auto-air-condi...apter-fitting-kit-universal-for-all-vehicles/
R12 http://bmwe32.masscom.net/johan/aircon_R134a/R12_coupling.jpg
R134a http://bmwe32.masscom.net/johan/aircon_R134a/filling_adaptors_installed.jpg

 

Done
