direct 12 volts. maybe attach a rubber hose on one end to blow air to test the flow. After applying 12 volts, the element inside should get warm/heat and makes the valve close. when cold and blow air on one side, you should feel the air from the other side. offcourse when valve close, you can feel lesser air (i think not totally close but u will notice less air)

You don't need a cold start valve in San Diego. If you aren't sure it works right, remove the hose and plug it. Disconnect the wiring. Continue driving.

Ah...this tests the AAR, not the CSV.
