An improved method and article of manufacture for introducing a locator wire into an interior portion of a pressurized, or non-pressurized, subterranean or otherwise concealed plastic pipeline. The present invention introduces a locator wire into a plastic pipeline while simultaneously minimizing the escape potential of a transported volume, such as, but not limited to, gas, water, sewerage or oil. A locator wire feeding unit initially feeds the locator wire through a locator wire alignment coupling and proceeds thereafter to project the locator wire through a valve assembly, a locator saddle, and ultimately into a plastic pipe.
