Unfortunately I found out that Pioneer need signal from the handbreak not just an earth.

A couple options for you. Keep in mind, I've never worked with steering wheel controls with aftermarket HUs....

Option 1: Look under and into the handbrake. I remember seeing a button down there when I was messing around with the center door lock switch (I have a 2008, can't remember what the 2012 looks like). I believe that button is pressed by the handbrake, which turns off the handbrake light. You can try tapping into one of those wires???

Option 2 (probably the better, but more expensive route):
Get these two items for a splice-free install to control you steering wheel controls.

If going with option 2, please read through everything to make sure your Pioneer HU would be compatible.
