I have a cable Tach off a 4Runner of the same year and motor to install on my truck. I know I have to change out the oil pressure switch in order for it to work with the new tach. Does anyone have a part number, or can I just get one at autozone giving them the info for a 91 4Runner?
he means to go from the idiot light to the gauge, and yes you will need a new one. auto parts stores should have it.
