We take this cable: http://www.pimfg.com/Product-Detail/ID-22

splice it to the two leads on the valve, solder it and cover with heat shrink tubing

we use this valves: MAC 46A-AA2-JDAA-1BA

The valves are super easy to work with and for our usage we only have one solenoid to deal with.

Easier than dealing with the two solenoid, and much cheaper. About 40 bucks. And the wire above is much easier to deal with.
