Product Description

Our Pro-Series is ideal for those looking for the best aesthetics, weight savings and reliability. Completely replace your old harness and forget about electrical gremlins. Dress up your bay and take all the pain out of wiring work with this harness.

This Wiring Specialties PRO Series harness was designed from the ground-up, specifically for a LHD or RHD Z32 300zx or Fairlady Z (90-98) with an RB25DET S1/S2 engine swap. It was developed in house on an actual RB25DET engine to ensure a perfect fit to all engine sensors.

The harness is designed 'Tucked' for a clean installation. The harnesses are built to exceed OEM spec for wire quality and power/ground routing.
