Patrick - I think you missed your calling in not becoming an electrical engineer - but it probably pays less than your current occupation. I'm drawing a blank on that 50 amp circuit breaker sitting in front of the battery. Being too warm and comfortable to walk out into the cold garage to study my car some more - I wonder if that circuit breaker is on the firewall now, just to the right of the starter solenoid in this picture? The wiring diagram appears to show it connected to the positive battery terminal at the relay.
