While most electrical systems in your Mitsubishi GTO/3000GT, aside from the ignition coils, won’t electrocute you there is plenty of scope to cause a fire, burn yourself or cause expensive damage to your car.

Some diagnostics require the car’s electrical systems are powered on. Where this is not required we advise disconnecting the battery negative terminal. Take care not to cause short circuits and not to apply excessive strain on the wiring loom and electrical connectors. Do not disconnect any connectors with the ignition on unless specifically advised to do so.
