Your big fat ground wire from your block should go directly to your negative battery terminal. Otherwise your big ground wire wire tend corrode faster at each connector end as it passes the starter amperage. The second ground wire that you connect from your negative battery terminal to your frame then only has to be a #10 or #12 wire to service the return path for your lights, fan, and tunes. Electricity takes the path of least resistance, so if it is jumping to your console from the shifter, you have some major resistance in your big ground wire or corrosion at the connections.
