914Rubber Alternator Harness Electrical Connector for Porsche 914 (1970-76)
PMB Performance has been the heartbeat of Porsche 914 restoration for over 20 years, and our nearly two-decade alliance with 914Rubber makes us the top retailer of their SKUs worldwide. The 914Rubber Alternator Harness Electrical Connector for 1970-76 Porsche 914 models (1.7L, 1.8L, 2.0L) is a precision reproduction that keeps your charging system rock-solid.
This connector (replaces OEM 021 971 349 D component) is a heat-resistant, injection-molded nylon plug designed for both ends of the alternator harness, though the alternator-side often fails first due to heat exposure near the 55-70A Bosch unit. Rated for 30 amps and 14-16 gauge wire, it ensures a secure crimp connection to the 914’s 12V system, preventing voltage drops that can dim lights or starve the D-Jetronic ECU. Its OEM-spec 4-pin design locks firmly into the alternator and regulator board, resisting vibration up to 5,500 rpm. Two connectors are required per car.
Our techs, with thousands of 914 harness swaps behind them, know these connectors withstand engine bay temps of 200°F+, unlike brittle stock plugs that crack after decades. Made in the USA, each is dielectric-tested to 1,500V for insulation integrity, ensuring no shorts in your 50-year-old wiring. Pair with 914Rubber’s harness grommets for a full refresh, and check terminal corrosion before install for best results.
