The engine wiring harness ties the PCM to the DBW throttle body, fuel injectors, coils, and sensors so the swap fires up and runs. It suits builders putting a 4.8, 5.3, or 6.0 into a project car or truck.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStand alone layout removes the need to strip down a factory harness\u003c\/li\u003e\n\u003cli\u003eDrive-by-wire ready for DBW throttle body setups\u003c\/li\u003e\n\u003cli\u003eTagged and color-coded circuits for simpler routing\u003c\/li\u003e\n\u003cli\u003eBuilt for LS-based 4.8, 5.3, and 6.0 engines\u003c\/li\u003e\n\u003cli\u003eFused power and relay provisions for key-on circuits\u003c\/li\u003e\n\u003cli\u003eGM-style connectors for common LS sensors and injectors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFits These Machines\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003efor LS3 drive-by-wire swap builds\u003c\/li\u003e\n\u003cli\u003efor 4.8L LS engine swaps\u003c\/li\u003e\n\u003cli\u003efor 5.3L LS engine swaps\u003c\/li\u003e\n\u003cli\u003efor 6.0L LS engine swaps\u003c\/li\u003e\n\u003cli\u003efor 2003 to 2007 drive-by-wire applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eEngine swap projects moving an LS into a classic car or truck\u003c\/li\u003e\n\u003cli\u003eRestomod builds needing a clean stand alone harness\u003c\/li\u003e\n\u003cli\u003eOff-road rigs running a carbureted-to-EFI conversion\u003c\/li\u003e\n\u003cli\u003eShop builds wiring an LS on a run stand\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecs At A Glance\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHarness Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eStand alone engine wiring harness\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eThrottle Style\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDrive-by-wire (DBW)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEngine Fit\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLS3, 4.8, 5.3, 6.0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eYear Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2003 to 2007\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch4\u003eGood To Know\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Will this harness work with a cable throttle body? \u003cstrong\u003eA:\u003c\/strong\u003e No, this harness is set up for drive-by-wire throttle bodies and requires a matching DBW pedal and PCM tuning.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Do I need to modify it for a 4.8 or 5.3? \u003cstrong\u003eA:\u003c\/strong\u003e The harness is built to cover the common LS variants, but pinout and sensor differences should be confirmed against your specific engine before install.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eSlight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.\u003c\/em\u003e\u003c\/p\u003e","brand":"Solid Spare","offers":[{"title":"Default Title","offer_id":50554665664598,"sku":"ZZ3N01105","price":189.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0697\/8460\/0662\/files\/s-l1600_8f5ad8d9-af6e-4719-9d44-7bf9f71e7fda.jpg?v=1790902212","url":"https:\/\/www.solidspare.com\/products\/t56-dbw-engine-wiring-harness-stand-alone-ls3-for-4-8-5-36-0-drive-by-wire-03-07","provider":"Solid Spare","version":"1.0","type":"link"}
