SFENA Gyro Horizon H301BDM

Hi All,
Can somebody help please. I have a SFENA Gyro Horizon H301BDM i would like to fit into my Pioneer.
Fitting is no problem but i have no idea what the power requirements are. So what pins require what voltage and how many watts will it consume?
As i’m VFR only the back light is not required. Many thanks in anticipation.
