You cannot drive this make and model vehicle with the speedometer disconnected because the transmission will not shift out of low gear. It is possible to reset the odometer electronically, however, in most states it is illegal to do so. 1991 Chevy Cavalier 4 cyl 2.2. The speedometer stopped working.
Nothing is digital.
Everything is completely basic. I looked for a cable behind the dash. Not even anything close to a cable. Looked around the engine for a sensor or cable. I'm pretty lost now.
