I have found what appears to be the electrical distribution block, but it looks nothing like the one in the service manual.
here is what I have:
the block, seperated into three portions. Connected to the top terminal section from the left side is a blue wire which goes to the block and seperates into a blue wire and green/red wire which come out onto the right side. These wires are joined at the block with a Phillips head screw.
Next section down, from the left I have two red cables joined to the block with a bolt and comes out the opposite side to a single red cable. the third section is joined phsically by a metal plate, and has a red cable coming off of it on the right side.
Below the block, i have connected to the fire wall a black cable that goes into a black 'bullet' appox. 2" by 3/4" tapered 1/2" at ingress and egress points. The egress point has a single black cable coming out.
Below this 'bullet' I have what I believe is probably the #16 connector. It has two wires going in and out of it. when you pull the cable connector apart it appears that the connector is silver plated copper. I cannot determine the color of the wires going in other than that one is light and the other is dark.
Let me know how off base I am.
