Ok, according to my manual, the SECOND wire from the LEFT end with the "tab" on it (looking into the connector with the lock tab facing you), is the TACH driver wire. It appears as though this would be the SECOND wire from the front (connector tab facing the fender).

No, it's the connector for the EDIS (Electronic Distributorless Ignition System) module that is bolted to the LEFT inner fender, just behind the relay box. It should say EDISS on a white tag on the top of the module.
Oh, yes you need a Ignition switched power supply, (you can get that in the fuse panel) a ground, and the light is optional.
