The fuel pressure sensor easily identifies these engines, early engines use a 4-pin fuel pressure sensor. GM uses two different fuel pressure sensors with the Gen V LTx engines. Depending on which one your engine has, will determine which harness is required. The Sensor is mounted to the back of the driver-side fuel rail.\u003c\/p\u003e|\u003cp\u003eEarly LTx engines\u003c\/p\u003e","brand":"Holley EFI","offers":[{"title":"Default Title","offer_id":46731735072907,"sku":"HOL558-220","price":214.13,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0554\/5495\/7707\/files\/hol558-220-holley-efi-fuel-injection-harness-pn-558-220.png?v=1777034984","url":"https:\/\/jbspowercentre.com\/products\/gvmr-558-220","provider":"JBs Power Centre","version":"1.0","type":"link"}
