Link-LSU 4.9 Plug Kit (PKLSU)

✅ Purpose-built for LSU 4.9 wideband sensors — this kit provides the correct plug, pins, and wiring harness needed for a clean, OEM-style installation when using wideband O2 sensors with Link ECUs (such as G4+/G4X Fury, Thunder, or CAN-Lambda setups). 

🔧 Plug-and-play wiring — eliminates guesswork and reduces error risk compared to DIY wiring jobs. The mating connector ensures proper pin alignment and secure connections, making installation easier whether you’re replacing a worn sensor or doing a fresh build.

📊 Reliable AFR monitoring setup — when combined with a compatible LSU 4.9 sensor, this plug kit lets the ECU accurately interpret air-fuel ratio data, which is critical for tuning, fuel mapping, and preventing lean/rich conditions under boost or high load.

🛠️ Compact and universal wiring harness support — ideal for retrofit installs, custom engine swaps, or performance builds needing a clean wiring solution without cutting or splicing factory wiring.

🔌 Recommended for any wideband install or sensor replacement — if you’re upgrading your ECU’s feedback system or replacing a failed sensor, this plug kit ensures you get the correct connector interface from the start — no soldering or special wiring kits needed.
