{"product_id":"vortec-standalone-wiring-harness","title":"Vortec Standalone Wiring Harness","description":"The PSI Conversions HAR-1015 is a standalone wiring harness specifically engineered for retrofitting 2003-2007 GM Vortec engines (4.8L, 5.3L, 6.0L) into older muscle cars, street rods, or non-emissions controlled vehicles. This harness is designed to work with Drive-By-Wire (DBW) throttle systems and is compatible with T56 manual transmissions, as well as non-electronic automatic transmissions such as the TH350, TH400, Powerglide, 700R4, and 200-4R.\n\nIt features comprehensive connectivity for critical engine and transmission functions, including connections for the fuse\/relay box, fuel pump control (relay included), fan controls, check engine light, speedo and tachometer outputs, OBD2 port, accelerator pedal, throttle body, MAF sensor, MAP sensor, engine coolant temp sensor, alternator control, two upstream oxygen sensors, crankshaft position sensor, camshaft position sensor, fuel injectors, coil packs, automatic or manual transmission control, and knock sensors. The harness supports the factory Vortec intake manifold and Multec injectors, with optional support for flex-fuel (EV6) injectors.\n\nConstructed from brand new GM Delphi connectors and high-temperature TXL (Polyethylene Cross Linked) wire to GM specifications, this harness is built for longevity and reliability. It features a sliding grommet seal for a professional, leak-proof installation and typically provides 4-5 feet of length from the cylinder head to the PCM mounting location. All harnesses are 100% quality inspected before shipping.\n\nInstallation of this harness requires PCM VATs (Vehicle Anti-Theft System) removal. Optional accessories such as a C10 swap pedal, Vortec pedal, Corvette pedal, braided loom kit, E85 flex fuel signal wire (custom tuning required), engine ground kit, O2 sensors, TCC\/brake switch kit, and specific alternator or cruise control setups can be added during purchase. Custom tuning is required if the E85 Flex Fuel Signal Wire is added.","brand":"PSI Conversions","offers":[{"title":"Default Title","offer_id":52664208228664,"sku":"HAR-1015","price":549.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687146155.webp?v=1784335182","url":"https:\/\/store.motormia.co\/products\/vortec-standalone-wiring-harness","provider":"MOTORMIA","version":"1.0","type":"link"}
