Those should do it for you. Also make sure all connection points are clean.

What about the battery to accessory fuse block? Isn't there also a negative to chassis? I guess that would make 5 then...

If you're looking to upgrade for audio, then you want to make sure to upgrade the alt + to battery +, battery - to ground, and engine block/alternator - to ground.

That'* how I've always seen it done on the car audio forums.

To allow power to flow better, especially when you have power hungry electronics.

You can do it a number of different ways. Some people leave the factory wiring, and run additional wires. I removed the old wires and replaced them with 2 gauge power wire that I crimped gold ring terminals on to.
