Still fiddling with my truck and I found out near the steering wheel, in the centre of the pic there is a weird knob. I didn't push it because I know my rig has some issues going on and I didn't want to push a random event on the top of it. I read the owner's manuals I could find, but they didn't show/mention it.
It's a 91 Petrol with 3F-E and automatic gearbox.
Would you know what this thing could be please ?
