1. An injection molding apparatus comprising:
a manifold having a manifold channel, said manifold channel receiving a melt stream of moldable material from a source;
a nozzle coupled to said manifold, said nozzle having a nozzle channel for receiving said melt stream from said manifold channel;
a heater and temperature sensor coupled to said nozzle;
a valve pin slidable through said nozzle channel of said nozzle, said valve pin being movable by an actuator; and
a distribution assembly located adjacent to said manifold, said distribution assembly having at least one distribution member, said at least one distribution member including,
a groove provided in an outer surface of said at least one distribution member, said groove for receiving wiring from said heater and temperature sensor and routing said wiring to a termination location on said injection molding apparatus, and
a first conduit and a second conduit extending through said distribution member, said first conduit for transporting a fluid from a source through said distribution assembly, said second conduit for returning the fluid to the source.
