Quoted from Manny65:
Exported games often didn't have the service port wired in however it is possible to fit one if you need
Thanks, I did not know it was possible !!
I'll try to find a european equivalent, that would be more practical
Alternatively, anyone has experience on wiring a Meanwell PSU directly to main power input ? Need to find if it's easy to access the main power lines and splice the input
[EDIT] Well I found all I need on Pinside and various sources. Hopefully the metal cover for my breakbox will allow me to route wire through or even better add the service outlet
