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 USDM LHD S13 240sx (89-94) with a NA SR20DE engine swap. It was developed in house on an actual SR 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.

Wiring Specialties offers a number of options for common performance upgrades for this product.  Build your perfect harness by selecting from the available options to the right.


Engine: S13/S14/S15 SR20DE

  • Any RWD naturally aspirated SR20DE engine from S13, S14 or S15 chassis.

Chassis: LHD USDM S13 240SX

  • Any USDM LHD S13 240SX manufactured in 1989-1994 (Including the Convertible and ABS cars)
  • Retains factory A/C, speedometer (conditional), tachometer, engine temperature gauge, oil pressure sensor, alternator charge light, reverse lights and wipers
  • Harness includes ABS sensor wiring on all S13 models

SR20DE Specific Details:

  • NOTE: The S13, S14 and S15 SR20DEs do differ in ECU and engine wiring. The actual harness will be finished to the specifications selected in the order
  • When using the S13/S14 SR transmissions, the speed sensor from these transmissions will be wired in and will allow the speedometer to function
  • The S15 SR20DE 5-speed Transmission does NOT have a speed sensor and the speedometer will not function. A S15 differential should be used to generate a speed sensor signal. This option must include the SGI5 frequency modulator to allow for calibrating the speed signal and accurately display the speed
    • **For aftermarket ECUs and Speed/Density conversion, the harness will include an IAT sensor and a MAP sensor connectors instead of the MAFS connectors
    • ** Most aftermarket ECUs will require conversion to coil on plug ignition system.
    • The ECU Patch harness is just an extension of the ECU connector, usually used for tap-ins and pickup points without having to damage the actual engine harness.
