Has anyone realized on the pontiac 2001 gt under the radio in the little storage area there is a little knob in the back what is that knob for?
probably to open a compartment for the dianostics port
its for the diagnostic port atleast i think
No idea what it is for... but the OBD2 port is under the steering wheel
That knob is not stock. It could be a hidden switch of some sort. I have 7 rocker switches under there for my lighting mods.
