Hello I got a question ,I just bought a 1992 corvette coupe about a month ago the car rides and looks great, but I did notice that there is a flashing SYS message on the digital readout display by the speedometer, I was told and seen by reading other threads on here that this can be caused by installing an aftermarket stereo in the car,well the car when I bought it has a aftermarket JVC stereo installed in it. Is there any truth that this can be the cause of it? I had the battery checked and even installed a new alternator but the message is still there. I seen postings on here that you need to install 2-1 ohm,1/2watt resistors to the yellow power wire of the car and then attach each other end of the resistor to the two open circuit dimmer switches, has any one out there dealt with this issue and maybe give me some insight on it? thanks
