On the back side of the alternator where the big hot wire to the battery goes, there also are 2 wires coming off of there with fusible links.
Those 2 wires feed your vehicle with power.
There is also 1 more wire coming off the battery positive terminal with that disconnect, follow that towards the fender and there is a fusible link.
Behind your computer in the engine compartment is this big tube plug on the wiring harness by your PCM plugs. With your battery unhooked unplug that big tube style plug. You may notice there as some melted terminals inside there. Not sure what they go to, I just know it's common for them to melt and there's some heavy red wires to/from that plug.
