So now its hooked up with Jumper wires, and not plugged in directly?
If yes, did you connect the two grounds on pin 25 and 39?

You can plug it into the Pi Zero, and your pirate audio in on top of that.
Then wire your relay etc to the proto zero. I used one with my Pirate Radio to add my own bigger buttons.
