Porsche 911 DME Switch Unit Wiring Harness - 1986-89
Part Number: 91161217309
Replacement wiring harness for the DME switch unit fitted to Porsche 911 G-model vehicles with Motronic engine management systems. Designed as a direct replacement for damaged, aged or deteriorated original wiring harnesses used with the DME control unit system.
The DME (Digital Motor Electronics) system controls critical engine management functions including fuel injection, ignition timing and engine operation. The wiring harness provides the electrical connection between the DME switch unit and the vehicle wiring system, ensuring reliable communication and correct power delivery to the engine management components.
Over time, original wiring harnesses can suffer from brittle insulation, heat damage, corrosion or poor electrical connections, especially in rear-engined vehicles where engine bay temperatures are high. Faulty wiring can cause intermittent starting problems, poor running, ignition faults or complete DME failure. Replacing worn wiring harnesses helps restore reliable engine management operation and electrical integrity.
Manufactured to match original specifications for correct fitment and connector compatibility. Ideal for restoration work, engine repairs or resolving electrical faults within the DME system.
