i had my speedo disconnected because i did not want to have to go through emmisions. i disconnected it right below the speedo itself in the gauge pod i disconnected a gray wire with black plug. i reconnected it and now the speedo is not working. does anyone know why , that was the only thing i disconnected.
car is a 91 rs

 

i just drove around the block the speedometer is still not working, however the odometer is working fine. i also have all the trim off and the gauges exposed i can here like a buzz sounds like an electrical buzzz it is going on and off every few seconds.
