{"product_id":"ft450-550-4-cylinder-universal-a-harness","title":"FT450\/550 4 Cylinder Universal A Harness","description":"\u003cp\u003eThe FuelTech Universal 4 cylinder A harness is a great addition to any 4 cylinder build and can be used with both the FT450 and FT550 ECU’s in a complete plug and play style. It is to suit 4 injectors and 4 individual smart coils, wired in semi-sequential fuel injection and wasted spark ignition. It can be used with high or low impedance injectors; low impedance requiring the use of a peak and hold driver, high impedance requiring a peak and hold jumper harness (both sold separately). The harness is set up for either VR or Hall effect cam and crank sensors and includes 3 relays with built in fuses for main electronics, injectors and coils. The universal 4 cylinder A harness has a label for each connector and the insulation is heat, moisture and oil resistant.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e4 EV1 injectors\u003c\/li\u003e\n\u003cli\u003e4 Smart coils\u003c\/li\u003e\n\u003cli\u003eFuelTech Peak and Hold external drivers ready\u003c\/li\u003e\n\u003cli\u003eFuelTech WB-Nano O2 ready\u003c\/li\u003e\n\u003cli\u003eGM style intake air temperature sensor ready\u003c\/li\u003e\n\u003cli\u003eGM style engine temperature sensor ready\u003c\/li\u003e\n\u003cli\u003e2 pressure sensors ready for fuel, oil \/ another 0-5V sensor\u003c\/li\u003e\n\u003cli\u003eExtra output connector for generic use\u003c\/li\u003e\n\u003cli\u003eCrank and CAM connectors (hall and VR options included)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis harness was designed for systems with up to 4 injectors, 4 smart coils and a FuelTech Wideband Nano O2 with Bosch LSU 4.2 sensor. It's setup to run semi-sequential or multipoint injection and wasted spark. It is already wired for FuelTech Peak and Hold drivers when using 4 low impedance injectors. When using high impedance injectors, a Peak and Hold driver is not needed and in this case, only a bypass connector (jumper wires sold separately) is required. There are 3 separate relays to power the whole system, separating the injectors and coils from the electronics.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTo activate coils and injector relays the Blue#6 output must be configured as Fuel pump or RPM activation.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003e*This is only the A harness which is all the FT450 requires.\u003cbr\u003eIf you are using an FT550 and want to use all of the extra inputs \u0026amp; outputs, you will need to purchase the B expansion harness as well.\u003c\/em\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"H6 Racing","offers":[{"title":"Default Title","offer_id":51493715935465,"sku":null,"price":2199.99,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/4340\/3241\/files\/products_FT450_5504CylinderUniversalA_540x_0b610337-4632-4cc7-aabb-3e52540acf41.webp?v=1783414205","url":"https:\/\/h6racing.com\/products\/ft450-550-4-cylinder-universal-a-harness","provider":"My Store","version":"1.0","type":"link"}
