My understanding would be that in this picture:
The #1 post at the top of the picture should be connected to the blue wire that comes from the warning light on the dashboard.
The #2 post on the lower left should be connected to the ground wires, one of which goes straight to the top of the engine.
The #3 post on the lower right should be the thick red power from the battery.
Is this correct?
