If it goes to that relay AND to ignition somewhere (trough dashboard bulb or wherever) you have found your problem.
The blue wire goes to the relay to let it know when the engine is running, so the screen is only heated when the engine is running and can't be used when engine is off (that is the standard Ford wiring)
It does not go to ignition, although it was turning the relay on and that could have been feeding power back to my ignition
The relay should never have been there.
I don't know how these relays work so i can't figure out what it is sending power too.
