Grote 66904 Sentry Ground Return Slim-line industrial wire

Grote 66904 Sentry Ground Return Pigtail

This Grote 66904 pigtail provides a factory-moulded ground-return connection for Sentry-series lamps. It carries three 14 AWG GPT wires terminated in a slim-line 0.18 in male bullet connector. The assembly measures 6 in overall with a 5 in wire lead and includes four connectors in a blue housing. It is designed for direct fitment to compatible lighting units.

O-ring seal and factory-moulded plugs

An integrated O-ring helps prevent moisture and corrosion at the connection point. The factory-moulded plugs eliminate the need for field crimping or soldering, reducing installation time and improving joint reliability. These features protect the circuit in harsh automotive and industrial environments where vibration and exposure are common.

Fits 5202, 5206 and 5306 series lamps

This pigtail suits technicians and fleets repairing or retrofitting Grote 5202, 5206 or 5306 series lamps that require a three-wire ground-return configuration. It is not suitable for lamps using a different connector style, wire count or pin spacing. Buyers needing a two-wire harness or a non-Sentry interface should select an alternative part.
