Description

The Jackspania K20 K24 K-Series Tucked Engine Harness is engineered for K-swap cars, offering a super clean look by tucking wiring away. Constructed with SAE certified automotive-grade wiring, the harness is resistant to moisture and most solvents for durability. It features military-grade heat shrink loom that is gas and diesel resistant and rated for extreme temperatures (-55° C to 150° C / -67° F to 320° F). The tucked design includes a layout where the main harness runs over the valve cover, and injector plugs come up from under the manifold. RDX injector plugs are included, with the option to fit their pins into OEM RSX Type S 310cc plugs. The power wire is thin yet high-grade, suitable for fuse boxes in factory or relocated positions. All necessary plugs are included, except for EVAP and AC. Each plug is clearly labeled for straightforward installation. Key features include a tucked design, harness routing over the valve cover for a clean appearance, compatibility with stock or relocated fuse boxes, and injector wiring that runs from under the manifold. It also has a relocated ground wire and includes a single-wire temperature sensor wire for stock clusters on K-swap cars. Three auxiliary wires run from the ECU to under the intake manifold, with two pre-installed ECU pins. An extra knock sensor plug is also included. Each harness is inspected and tested before shipping. The new design utilizes factory RSX connectors. This product will NOT fit RHD (Right-Hand Drive) or RWD (Rear-Wheel Drive) cars.
