how are you guys plumbing the humphrey 31012vdc solenoids with the holley terminator X....im using a dual solenoid setup but not sure what ports to plug off? also does anyone happen to know what wire is the positive and negative on the solenoid?

Not polarity sensitive unless there is a diode involved. On DC wiring, black, blue w- white stripe or brown is generally 0vdc or negative wire.

I’m sure you know one will be your fill and one your vent. They should tie together with a “T” fitting. For the fill solenoid, I believe you’ll plug the #3 port, pressure source to the #1 port and the #2 port will have the “T” fitting. For the vent solenoid, port #1 will go to the “T”, port #3 will be plugged and port #2 will be your vent. As far as wiring, I don’t think it matters which wire has power or ground.

my valves have the number 3 port on the side that i both currently have plugged. i just wasnt sure if the ports in different locations was gonna matter compared to the location of the holley valves.
