Solenoid Recommendations

[jfitz0807]

We're planning to go with a setup like s_forbes. We have a 1.5" bore, 4" throw cylinder and we're shooting reasonably well using just the standard Vex solenoid/manifold through about a foot of tubing to the cylinder. We're optimistic about using the higher flow solenoid directly connected to the cylinder.

We're trying to figure out how to wire the solenoid. The picture only shows "12V" with arrows pointing to the two parallel leads. I'm not sure what that means. The PCM only has a black and a red wire. Do we connect red to one and black to the other? Does it matter which is which? What do we do with the third lead?

And oh, by the way, we'll be using 24V so we'll get a 24V solenoid.

Any guidance is appreciated.
