Im about to do the Big 3 I am about to do the big three on my car and had a couple questions. First, why is no one replacing the positive lead from the battery to the fuse/distrobution block? Second, are you removing the old wires or just adding the new ones? Third, is there anywhere i could see some pictures of this, it seem like the pictures were deleted on all the threads that had them, or my computer is crapping out.

its called big 3 for a reason lol, only need to do battery to alternator, battery to chassis, engine to chassis. You dont have to remove the old wire because electricity will take the path of least resistance. Some take the old wires out to clean it up a bit.

So whats the reason? To me it seem like if you dont upgrade the battery to the fuse/distribution block you are missing a step. Isin this the point where the car pulls power for the electrical system? The only thing i can think of is that the draw on that point isnt enough to warrent it but it couldnt hurt.

leaving the stock wires on (in addition to the BIG3) will reduce the overall resistance of the system.
For example, lets say your old wire is 1ohm and you new wire is 0.5ohm. If you replace the old wire with the bigger wire then you have decreased the resistance from 1ohm to 0.5ohm, but if you use both wires together you have reduced the resistance from 1ohm to 0.33ohm. But it would look a lot cleaner if you just used the BIG 3 wire.

We run our amp wires from our batteries. The amp wire thus does not travel across the wire that goes to the main fuse block, so it doesn't need to be upgraded. You can upgrade it if you want, though. If you have extra wire and get bored, go for it.
.................................................. .......(separate wire) -> amp
Alternator -> (upgraded wire) -> battery <
.................................................. .......(stock wire is fine) -> fuse block (no more power is being drawn here)
