Description
Product Overview
The HiSport Ignition Coil Harness Wire Connector set includes two precision‑engineered connectors designed to replace OEM lead wires on a variety of truck and performance engines. Manufactured from heat‑stable silicone‑tressed copper conductors and a reinforced PVC jacket, the wires maintain signal integrity under high‑load conditions. Each connector features color‑coded pins (green, red, purple, etc.) that correspond to specific cylinder firing orders, reducing installation errors. The set complies with OE numbers LSX‑RELOCATION, C1208, D581, UF271, DAC044, and 1143‑5H, ensuring a direct fit for popular models such as LS2, LS7, D581, D585, and D513A.
Usage
Designed for both professional mechanics and DIY enthusiasts, these connectors are ideal for rebuilding or upgrading the ignition system of Chevrolet, GMC, and Cadillac trucks with 4.8L engines. They perform reliably in high‑temperature engine bays, making them suitable for daily driving, off‑road adventures, and track use. Installation requires matching the colored wires to the corresponding coil terminals—green to cylinder 4 or 5, red to 2 or 7, purple to 1 or 8—ensuring optimal spark timing and engine performance.
