Whelen pccs9r wiring help

[eng18ine]

Hey guys. I'm not sure what's wrong with me but I can't seem to get this to work. I'm trying to wire up a whelen pah112 to the momentary switch on the pccs9r I have the pah powered but I can't get a signal out of the momentary switch. Am I missing something here?

The momentary switch (S7) is isolated and requires it's own +12V fused supply to pin 11 10. See last page here: http://whelen.com/install/133/13315.pdf

I read that whole manual from whelen. I guess I just missed it. But thank you. That's exactly what my issue was.

Sorry to dig up this old thread but I'm confused with this. Pin 10 gets 12v power correct? So what gets plugged into pins 11 and 12? Is one ground then the other to the accessory?

Pin 11 is  common, Pin 10 is normally open, and Pin 12 is normally closed.
