Need code written to hook up motor and momentary switch to another mechanism. I need to put a current sensor on a wire to a solenoid (12vdc I think) when the solenoid trips I need the Arduino to send out a signal to a relay and keep it on for 5 sec, and also a signal to a sound box.

I can make it as you've described. Also, with a solenoid you may try to use a reed switch as a sensor of the actuation of the solenoid. That even may more reliable.
