I think you might need the ECU as well as the Electric Load Detector unit (ELD). Daox is probably correct that it is a bit more complex. There are several wires into the alt... a 4 or 5 pin connector, IIRC. In fact, even with my switch, once I turn the alt on, putting the switch back into off does not shut the alt down, inly cutting the engine will do that. Works well enough.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.

My 2006 Acura TSX has a 4-pin control plug to the alternator. It de-energizes when the 4-pin is unplugged, and re-energizes when plugged back in. Output voltage is determined by the ELD (Electric load detector), which is one of the 4 wires going to the alternator.
