I don't know what wire is what, but Google should help you to find a PDF of the Helm manual for your car. (I know there's one out there for the CRX, which is just about identical mechanically to your car.)

Your car, BTW, already has an alternator disable built into it. The ECU reads a bunch of parameters like temperature and current electrical load, and turns off the field current to the alternator when it doesn't think the battery needs charging. It freaked me out when I saw that behavior the first time on the cheapie voltmeter that plugs into the cigarette lighter.

I used to drive my CRX with the fan on to force it to charge because I did a lot of engine-off coasting in it, including some with the lights on.
