Many of the modern cars will not run if the bags are disconnected, They will run but have codes if they were deployed. However looking at the wiring diagram I don't see any red wires going to the side curtain units or even as part of the air bag system. Red is normally used as a power feed color on Lincoln's. Does it have any other color or is it only red?
What other wires were around it? Could you take a picture and load it here so we can see the wiring.
