The Tucked Engine Harness is designed as a high quality replacement 02-04 RSX Type-S harness offers a look. We have made the harness with lots of features so it will work with nearly all K-Series engine swaps and the 02-04 RSX Type S.
It includes all the necessary plugs with a handful of extras (Fan Switch, IACV, Temp Sensor, ETC).
It is rated for -55° C to 150° C (-67° F to 320° F). We have also used a popular and clean tucked wire layout. The main harness runs over the valve cover and even hides the injector plugs, which come up from under the manifold. OBD2 injector plugs come with all harnesses.
On swap chassis, the power wire will work with fuse box in factory location or relocated under the dash. Separate power wire is available for other chassis and those prefer to run their own charge wiring. Everything is labeled clearly to a simple installation and no confusion.
