Wiring HUD 04 Grand Prix GT

[ULTRA MUFFINS]

Does anyone know which wire to splice into for the data to the hud, I believe it has power since I hear a clicking noise (presumably the motor inside) however I don't get any sort of display. Also is there anyway to test the hud to see if it fully powers up before completely installing it?

Update, it's displaying properly, except the pages button does nothing, and the motor isn't moving, any suggestions?
