Information colours on steering wheel

Hi,

I'm working on 2010 CSM personal mod and i've got a problem with steering wheel information.
I want to change the information colour on the steering wheel but i didn't find the right file.
I know how i can change the position with the "language".pos file but there is no line concerning colours.
Do you know the file which i have to modify ?

you won't find any colours, because there are only fonts for the steering wheel informations and the informations are stored in the folder gp4\ldata\english.3d

I'd just make a Highlit box for all the info. But then again there was the 199X mods.......
