Fuel Pump wiring question

[SHAWN056.0]

I recently put in an Airdog on my truck and wanted to wire the relay switch wire in with the stock fuel pump so the Airdog just comes on with the fuel pump. I can't seem to find out how this stinking thing works. I know there's a relay for the stock fuel pump.... what wire do i tap into? color? ect ect.. Thanks
