PGV wires
Hi Larry, those arrows are pointing in the direction you would turn the solenoid which will turn the valve on and off. For normal operation you want it closed (clockwise). Just turn it by hand til it's snug. The valve might shut off right away or take a few seconds. Give it a chance. The arrows aren't pointing at the wires. You can use either wire for the ground or hot. One wire will go to the common or ground terminal at the controller. One wire will go to the station number terminal on the controller.
Good luck!
If I can't fix it, it's broken!
