Disclosed is a leak detection cable that has an outer jacket layer and a four wire construction in a flat wire configuration that is twisted in a helix. Detection cables are disposed on the exterior surface adjacent openings of the jacket to allow for detection of aqueous fluids. The wire is twisted in a helix to allow adjacent detector wires to easily detect aqueous fluids. Disparate materials are used for the jacket and the coatings of the wires, to allow the jacket to be easily removed from the wires without affecting the integrity of the coatings of the wires. The four flat wire configuration is sized and spaced for easy connection to an insulation displacement connector.
