Are the linked pics of the distribution block not good enough?
You want pics of the distribution block actually installed?
My setup also includes a remote cut-off switch (with 80-amp solenoid to cut the alternator power feed too) and distribution blocks for two amplifiers and a capacitor so it's way more complicated than most people would have.
The only decent pics I have right now are these.
Both of the 4ga black wires and the black 8ga wire go to the chassis ground (through the kill switch). (A 4ga black wire comes from an audio distribution block and also grounds to the negative battery terminal through the chassis side of the kill switch.)
One of the 4ga red wires goes to a distribution block for the audio stuff. The other red 4ga wire goes way up front, throught a grommet in the firewall, near the old battery box location where it enters a
pass-through distribution block. The thick (4ga?) wire from the starter connects to the other end of that distribution block. The smaller 8-10ga wires from the alternator and fusebox and such connect to the side of the pass-through distribution block in the available spots.
Here are the distribution blocks for the audio, and one of the amps, and the capacitor.
Here's the kill switch. You'll notice the 16ga speaker wire that goes way up front by the alternator where it controls the 80-amp solenoid up there.
Also, here's a schematic I did way back before I did the install that describes exactly how it all works except the damn distribution block part up in the engine bay that you asked about. =/
