Trunk release relay

Hi, I hope any of you can help me with my trunk release wiring problem.

I recently installed a matrix 1 alarm in my car and I want to add a relay to open the trunk with the remote. My car has a factory release button, so the only thing I need is the relay, but the alarm gives a negative output and my selenoid needs a 12 volt(+) output, here is where my questions come: Can I do this with a simple 12 volt 5 pin relay? How would I conect the wires? Please help. I am not an expert in electrical wiring but I get arround somewhat. I you have a diagram it would be even better, if not, that is cool.

Jose
