Thanks to Al & the GDC for updating this. Although putting in the extra relief valve isn't that big a deal, there is a cost to it and more places for air to leak. Minimal safety benefit.

We always use single solenoid valve unless there is a design reason to use a double solenoid valve. The din connector that comes with the valve has the LED indicator as well. I like the cable assembly because the connector is potted. The wire pair are both black & numbered 1 & 2. They poke nicely into the PCM. Valve directions show terminal 1 as positive. I have not tested to see if that really matters, It matters on some DC solenoids and not on others.
