Typically, the brown wire in the balmar harness that hooks to the 4 pin connector is for the ignition signal.
The tach is usually a white wire either directly to the stator terminal on the alternator, or to the output terminal on the regulator.
I found a brown wire in the engine junction box. It was not connected. It does give me ignition switched DC voltage.
The brown wire coming out of the harness is spliced in the junction box to a wire that I can't determine the color. After it left the harness it was again spliced this time to a red wire. Here's where it attached to the original alternator. There is no voltage on this wire with the ignition on.

Is this possibly the wire for the tachometer?

If you download the Balmar Alternator manual, it'll explain the brown wire. Just search on "brown" in the pdf file.
......Are you sure the tach you have is already driven from the alternator?
Bmarler;
No, I am not sure. Looks like I will have to track the wire from the tach to the engine.
