Hi guys. Im at the planning stage on a pdm30 / pdm15 set up.
The only part I cant work out is how to wake the PDMs up. There does not appear to be a 12V in switch
when I look at the pin out.

Hi,
When power is applied to the 12V+ stud, and the two ground pins are wired to ground, then the PDM will turn on when power is supplied to the stud, it does not need another switch to turn it on.

I have a kill switch on the dash

Either cut the power to the pdm using a battery cutoff "relay/switch" or cut the earth's with the same.
What are you trying to achieve?

Just a switch outside of the can network that will turn everything off in emergency
fuel pumps mainly.

So you want a simple "master switch" input and set any outputs you want it to shut down.
