Attached is a picture of under my dash on my M923A1. I have put in the turn signal flasher and hooked it up. Also the light switch has been installed and plugs installed. But if you look right above the steering column you can see a black square area, it has a nut at the left end, and its indented like something was there.
Can anyone rake a pic of under the dash like this, so I can see what is there. Or does someone know what goes there. not the spot to the left but right above the steering column. It is a black square
Thanks
The black square is the fail safe warning for the air pressure and parking brake. It supplies the horn warnings and lights you see just above the steering wheel.
I'm not sure what the other plug is for perhaps the signal flasher control box ?
