Thanks for the suggestions. Disconnecting the connector on the dimmer switch was a big pia. Actually the gauges and turn signals did not work until I installed the electric fuel pump. Some dodge mechanic had hooked up the Mikuni cut off solenoid wire to the starter motor and that apparently was shorting out the dash. I do not remember the last time I drove it in the dark so I do not remember what the dash lit up is supposed to look like. But I would think that the turn signal lights would only come on when the signal was on.
