Wiring Specialties 1JZGTE non-VVTi Wiring Harness for S13 240sx - 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 engineered for a USDM LHD S13 Nissan 240sx (89-94) with the 1JZGTE non-VVTi engine swap. It was developed in house on an actual 1JZGTE non-VVTi engine in an S13 240sx 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.
