Im going to be doing the big three upgrade and i was just wondering if ive got the right wires. Positive to alternator, positive to starter, and negative to engine block.

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...

I followed the positive leads and theres just two, one to the alternator and one to the starter, and yes i found the chassis ground.

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.

kinda curious
why would you upgrade all this? whats the reason?

thanks

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

to help keep volts up. good for aftermarket audio n what not. on mine i did chassis grounds, batt neg to ground and alt to batt. running 2k RMS with a yellowtop under the hood and stock alt. works damn good in my setup hahaa

and what kinda wires do i upgrade too? and where do i get them from? lol

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.
