+Bryce R. Rickbeil: The wires going to the power relays from the raspberry pi should be set up as follows. The positive to the CDP instrument relay should be on pin 15 and the ground on any of the available ground options. Then the positive going to the relay to control the blower fans should be on pin 11 with the ground again being on any available option. The way to know which pins are grounds would be by going to this link and using this as reference to everything stated above. https://learn.sparkfun.com/tutorials/introduction-to-the-raspberry-pi-gpio-and-physical-computing/gpio-pins-overview
