QUESTION: Does the compressor clutch wire come from the relay,or would it come from the 15 amp fuse block? Also if it comes from the relay could I run a new wire from a 12 volt side of the relay to the compressor clutch? Thank you for all your help. Johnny

Answer
relay sends the power to the compressor.  You can run a new wire but make sure to connect it to the side on the relay that sends the power not the one with the power from the fuse.  I other words it will be one of the two grounds you have right now.  When relay is activated one will turn to power.
