Your amp gauge should work on 6 or 12 volts. If you are now negative ground you need to reverse the wire that runs through the loop on the back of the amp gauge. You can probably install the resistors without removing the gauge cluster. Remove the hot wire to the gas and oil gauge. Then install the resistors on the hot wire post of each gauge. Run the new hotwire to the first resistor and a jumper wire from that post to the other resistor.
