04 dakota that was crashed, hard hit right front, rebuilding, bags were deployed. On restart attempt I get P0685 & P0688 ASD relay codes. What controls the power that controls the relay? Does it go through the ignition switch?

These are power supply codes. See if the ASD relay is bad in the power distribution center. You might check for over heated terminals here is a guide to help you test the relay.
