- Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
Ensure proper harness alignment and electrical reliability in your classic Porsche with this Wiring Harness Mounting Plate, specifically designed for 911 models equipped with mechanical fuel injection (MFI) systems.
This precision-engineered plate serves as the main support structure for the engine wiring harness, securing cables, connectors, and ignition wiring to the chassis. It maintains correct wire routing, prevents movement or vibration, and protects electrical lines from damage due to heat, friction, or mechanical stress.
This plate is essential for maintaining factory-correct engine bay layout and reliability, especially in restoration projects or when replacing worn or missing harness supports.

What This Product Does:
Signs / Symptoms Of Wear Or Replacement Needed:
- The engine harness no longer stays securely in place, causing wires to sag or hang in the engine bay.
- Unsecured wiring can move or stretch, creating unstable electrical connections — especially in ignition and fuel injection circuits.
- Flickering warning lights, misfires, or erratic fuel injection behavior.
- Poorly routed cables can cross high-voltage ignition lines, introducing interference that affects sensor signals or ignition performance.
Why Replacement Matters:
- Cracked or hardened wires, which can break when moved.
- Corrosion inside copper conductors, increasing resistance and voltage drop.
- Loose or oxidized connectors, leading to intermittent contact or electrical arcing.
- Consistent current flow to the alternator, ignition coil, sensors, and fuel-injection system.
- Stable voltage readings, reducing risk of misfires, no-starts, or erratic gauge behavior.
- Frayed or melted insulation can short against the bodywork, risking sparks or even fires.
- Wires sagging near exhaust manifolds can melt and arc.
- Poor grounds or live shorts can damage expensive ignition modules or alternators.
