Description
Looking for the best in aesthetics, weight savings and reliability out of your harness? Our Pro Series harness completely replaces your old OEM harness so you can forget about those electrical gremlins.
This Wiring Specialties PRO Series harness was designed from the ground-up to exceed OEM specifications for wire quality, power/ground routing. With our optimized and ‘tucked’ approach the end result will be a clean and worry free installation with a guaranteed start up.
This harness is specifically engineered for a JDM RHD S13 Nissan Silvia / 180sx (91-98) with the RB25DET engine swap. It was developed in house on an actual RB25DET engine in a JDM S13 to ensure a perfect fit to all engine connections.
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, and as always – if you have any questions, please reach out to us.

AFTERMARKET ECU DETAILS
- If you are running an aftermarket ECU, we can customize your PRO harness to fit your exact build requirements. Click HERE to download and submit the ECU / Build details form with your order, or we will contact you once the order is placed to collect the needed details.
- AEM Infinity, Link and ECU Masters products (and some other standalone ECUs) are able to process a wideband signal input wired DIRECTLY to the ECU. The LSU 4.2 Version of the WB O2 Sensor SHOULD be used, as per AEM and ECU Masters. Select the Oval or Rectangular connector style in the options to match your WB O2 connector.
- All ECUs that are unable to process a wideband signal directly, will be wired for a FACTORY O2 sensor and a labeled flying lead will be provided to connect the ECU to the Wideband controller. For ECUs that do not process a raw wideband signal, a controller must be used. Controllers like an AEM UEGO Gauge Kit or the Haltech CAN wideband unit should be used.
- AEM Infinity, Motec, Link and ECU Masters harnesses are pre-wired for Oil Pressure, Fuel pressure, Oil Temp, IAT and MAP sensor wiring directly to the ECU. Flex Fuel support is available if desired. ECU control of a Boost Control Solenoid is also available on most harnesses.
- Apex’i PFC conversions ONLY include the IAT sensor in the main harness. The MAP sensor is wired separately, from the PFC box directly to the sensor. MAP sensor harness should be purchased with the PFC.
