Dash backplane??? these are all autometer gauges in a fast lane west insert all the gauges are grounded separate to one main ground--could it be the ground from the headlight switch this is also grounded separate--Steve this did not happen with gm headlight switch only with the mopar headlight switch that's why i think i got some wiring messed up when i switched back to the mopar switch
