VehOff.csv editing

I've been playing around with the vehOff.csv file to set up dashcams for the cars I use and have been playing around with the BONNET_FWD lines. I'm sure some of you know that following that, there are 3 numbers, each corresponding to the X, Y and Z position, does anyone know what order it goes in (Is it still X, Y, Z, or is it X, Z, Y or something else) and does anyone know what angle it is from (is it a top down view, meaning the X controls left and right, the Y controls forwards or backwards and Z controls up and down, or whether it's from the front meaning X is left and right, Y is up and down, and Z is forwards and backwards). Thanks in advance.
