A solenoid operated valve comprising a valve body having at least one solenoid unit mounted on an end thereof. Each solenoid unit contains a solenoid electrically operable to control valve means within the valve body. The valve may further comprise a manifold segment in fluid interface with the valve means. An automatic wireway device is provided comprising a modular wireway segment typically attached to the manifold segment. The wireway device automatically connects each solenoid to a selected electrical actuation channel. This connection is made by indexing plungers located within bores in the wireway segment. The plungers are movable upon engagement with similar plungers such that a contact means on the plunger is received into a radial detent having therein a channel contact. The channel contacts are each electrically conntected to one of the electrical channels. The contact means on the plunger is electrically connected to the soleoid. Typically, separate case ground and solenoid neutral conductors are contained within the wireway segment and also connected to the solenoid unit.
