This WS plus SIKKY LS1 Swap Kit is the markets only true turn-key kit for your LS1 swap. If you have an S13 240sx and an LS1 engine/trans, then this kit is all you need!

WIRING SPECIALTIES HARNESS  (scroll down for SIKKY Kit details)

The Wiring Specialties Pro-Series LS1 wiring harness is a Brand New, Tucked, Plug and Play harness that was designed and tested by our in-house experts specifically for a LS1 swapped S13 240sx. It was modeled on the actual LS1 engine and is race proven at Formula Drift.

Note: Coolant and Oil sensor adapters retain the use of factory Nissan Oil Pressure and Coolant Temp cluster functionality. The adapters are also machined to support most aftermarket temperature and pressure gauges that require a 1/8"-27 thread pitch. Will require the use of a Nissan S13/S14 Oil and Temp sensors (1-wire).

Note: LS2 and up engines, additional accessories and other injector types are subject to additional fees.
