Wiring Specialties S13 SR20DET Wiring Harness for S13 Silvia / 180sx (RHD JDM) - PRO SERIES

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 built as a OEM replacement for late model JDM S13 Nissan Silvia / 180sx (91-98) with the S13 SR20DET engine. It also works as a conversion harness for early model Silvia S13 / 180sx (1988-1990). It was developed in house on an actual S13 SR20DET engine in an S13 RHD chassis 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.
