What is the white wire (18 B/W?) with the fuse and the black wire engine harness with the fuse? Are those stock wires or something I need to add as well? I'm referring this picture.

The 2 black wires with the 2 small 4 amp fuses are stock original for the amp-meter to work. They stay as they are.
The red wires do connect to each other in the wiring harness. But don't jumper them at the alternator plug.
This want give you the correct reading.

The picture shows the stock bulk connector that is up by the drivers side head light. The bigger red wire goes to the bolt on the back of the alternator. The smaller red wire that was connected to the external regulator now goes to the #2 terminal.
The brown wire that was connected to the external Regulator now goes straight to the #1 on the alternator.
The white wire is terminated and not used.
You should run the small black ground wire over to the alternator also.
