Wire diagram for Cambles 1.1 powerboost Safe Shutdown?

[WoodMill]

Been trying to find a wiring diagram for Cambles 1.1 version of the Safe Shutdown Powerboost version. I've got both 1.1 and 1.2. I bought the 1.2 version because the 1.1 version wouldn't safely shutdown my GBZ. Second version does work.

But I have my first build of a GBZ without a safe shutdown switch and I want to wire this extra 1.1 version up to it, just to test to see if the switch is bad, or if it was my wiring.

But I'm having a hard time finding a wire diagram for the 1.1. I'm only coming across 1.2's. Anyone have the old diagram?
