Help with wiring issue on a 1967 Mercury 6HP?

[Mr. Asa]

I'm getting a motor that I've rebuilt ready for the water, and one of the things I needed to change was the kill switch. Using a multi-meter, I traced the wires from the old, broken switch, to the distribution block. Everything had continuity. There are 4 screws on the block, each screw had continuity to every other screw.

I can't find a decent wiring diagram, so I'm not sure if this is correct, although it doesn't feel right.

Does anyone have a wiring diagram for a motor this old?
