MaxxECU Race Terminated Engine Harness for Nissan 200SX CA18DET (RHD)

Product Overview

Terminated Engine Harness for Nissan 200SX CA18DET – Designed for MaxxECU Race

This is a fully terminated, plug-and-play engine harness tailored specifically for the Nissan 200SX CA18DET platform, designed to integrate directly with the MaxxECU Race. Built with high quality materials and a focus on clean, reliable wiring, this harness is a smart upgrade for anyone modernizing their CA18DET-powered build. If looking for a motorsport equivalent version, please contact us, we do offer a concentric twisted loom w/ DR25 sheathing on top.

Developed for RHD 200SX chassis, the routing has been designed for neat engine bay presentation and minimal interference. In some cases, you may need to reroute part of the OEM body loom through the inner wing hole to avoid contact with the new harness path. Final fitment mirrors what is shown in the product images.

This harness supports modern engine control features, DBW conversion, and common aftermarket upgrades—all without unnecessary splicing or guesswork.

Note: This listing is for the harness only.
