Hi
Have provided 12V and gnd to the 12v socket and not connected anything else.
Nothing lights up.
I do not have the optional power module.
AM I missing something?

so if you dont have the optional power module, you just put 12v/Gnd to the power socket, no switches nothing else?

The 12V LED on the MacArthur HAT will only turn on when the 12V switch is enabled, i.e. the 12V SW input is at 12V.
The 5V LED on the MacArthur HAT indicates when the (optional) power module is providing 5V. It will be off if power is provided by the Pi.
If you don't use the power module, both LEDs will stay off. The only reasons to connect 12V and 12V SW without the power module would be if you use the Seatalk or MAIANA connections. For Seatalk you need to connect GND, 12V SW, and DATA. For MAIANA you need to connect 12V, GND and 12V SW.
