Used to be B=battery, I=instruments.

Pretty sure you'll find:-

0v is chassis earth.
B is raw 12v input from battery.
i (instruments) is regulated 12v to gauges.

It's actually pulsed 12v to the gauges by means of a bimetallic strip constantly switching on and off. The gauges are so slow to respond they show the average reading. This gives an average voltage of 10v...

You can check it out by sending a variable voltage to a gauge, which also works on the bimetallic principle. Constant 10v gives a full scale deflection.
