Yes at your right foot and knee. open right door take away trim, and the cut off relays and x710 is there. X710 about 15 cm above floor, 3 relays bolted to right side around 50 cm above floor.
But don’t do what I did with 710, only reason I did this way was I could not find 3168 at the tractor ECU behind seat as fivefinnishfarmers did, so go the fivefinnishfarmers way, much easier. Also today PCB v4x can handle the pressure sensor directly.
In his thread at around post 70 you also find a stl for the 40 pin connector. I advise to read all posts from there to the end.
I think latest drawing from 23 pin on PCB to 40 pin CNH connector is here (Case CVX175 over CANBUS - #41 by FTyuste1234)
