As a after thought. The black wire in your hand is the wire to the amp meter. It is too small a gauge for the stock alternator and now that you plan to soup up the charging system it could easily over heat with more amps. So it should be up graded. The stock amp meter can be a fire hazard too. There are threads on this forum about that.
The "box" from PA Performance plugs in place of the stock regulator and you end up using one of the 2 smaller wires. They have their own diagram. The diagram from Tuff Stuff should get you going.
I had thought of getting a 3G from a u-pick salvage yard.
