{"product_id":"ls1-ls6-standalone-wiring-harness","title":"LS1\/LS6 Standalone Wiring Harness","description":"The PSI Conversion HAR-1012 is a standalone wiring harness engineered for retrofitting 1997-2002 LS1\/LS6 engines and electronic automatic transmissions, particularly into older muscle cars or newer non-emissions controlled vehicles. This harness offers a complete plug-and-play solution, requiring only four wires for hookup: switched power, constant power, and ground connections. It provides connections for essential systems including the fuse\/relay box, fuel pump control (relay included), fan controls, check engine light, speedo output, tachometer, OBD2 port, IAC and TPS, MAF sensor, MAP sensor, engine coolant temp sensor, alternator control, two upstream oxygen sensors, crankshaft and camshaft position sensors, fuel injectors, coil packs, automatic or manual transmission control, and knock sensors.\n\nConstructed with brand new GM Delphi Connectors and TXL (Polyethylene Cross Linked) high-temperature wire adhering to GM specifications, each harness is 100% quality inspected before shipping. The harness design includes a sliding grommet seal, offering a professional and leak-proof installation, and typically provides 4-5 feet of length from the rear of the cylinder head to the PCM mounting position under the vehicle's dashboard.\n\nThis harness is designed for use with specific PCM types (RED\/BLUE PCM, Service Number 411 or 896) and requires PCM VATs removal, which can be facilitated by PSI. Optional additions are available, including AC recognition, a DIY braided loom kit, E85 flex fuel signal wire (requiring custom tuning), an engine ground kit, O2 sensors, a TCC\/brake switch kit, and cruise control. When adding the E85 flex fuel option, custom tuning is explicitly required.","brand":"PSI Conversion","offers":[{"title":"Default Title","offer_id":52689687249208,"sku":"HAR-1012","price":400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687419759.jpg?v=1784909188","url":"https:\/\/store.motormia.co\/products\/ls1-ls6-standalone-wiring-harness","provider":"MOTORMIA","version":"1.0","type":"link"}
