The purple wire from the power relay needs to be connected to a "key on" power source (meaning it doesn't have power when the key is off, but does have power in the ACC or ON positions.) I have an addition fuse block connected in my truck which is connected to an IGN ON source. It has the full voltage from the battery. I plugged my wire into this fuse block and used a 10Amp fuse.
