Product Description
BP Automotive LS Swap Standalone Harness Fuse Block DIY Modification Kit with OBD-II Port
Fits 1993–2013 Gen II LT1 and LS-Based GM V8 Factory Harnesses
Convert a compatible 1993–2013 GM V8 factory engine harness for a standalone engine-management or LS-swap application with this BP Automotive DIY harness modification kit. Designed for both drive-by-cable and drive-by-wire harnesses, the package supplies the primary fuse, relay and diagnostic connections needed when reworking supported Gen II LT1 and LS-based wiring.
The kit includes a color-coded 12-way fuse block with six fuses, an ignition-power relay, fuel-pump relay, OBD-II diagnostic port, harness tape and a general installation guide. Fuse and relay positions are identified by a legend inside the cover, while the terminals are production-crimped to meet Delphi standards for crimp height and width. The panel provides the circuits specified for compatible 4.8L, 5.3L and 6.0L engine-management configurations.
Key Features & Benefits
- DIY Factory Harness Conversion Kit: Designed for modifying compatible 1993–2013 GM V8 factory wiring harnesses for standalone engine-management and swap applications. It supports both drive-by-cable and drive-by-wire configurations across the supplied Gen II LT1 and LS-based engine range.
- 12-Way Engine-Management Fuse Block: Includes a 12-position fuse block supplied with six fuses. The color-coded configuration and inside-cover legend identify the location of each fuse and relay, helping the installer organize and service the converted engine harness.
- Ignition and Fuel-Pump Relays Included: The panel arrives with dedicated ignition-power and fuel-pump relays as part of the engine-management circuit package. These components provide the primary switched-power and fuel-pump control connections required by the supported harness conversion.
- OBD-II Diagnostic Port: An OBD-II connector is included to provide the corresponding diagnostic connection within the modified harness. This gives the completed engine-management wiring a dedicated port for compatible scan-tool and ECM or PCM communication.
- Production-Crimped Terminals and Installation Supplies: All terminals are production-crimped to meet Delphi standards for crimp height and width. Harness tape and a general installation guide are also included to support an experienced installer completing the factory-harness modification.
Notes
- This is a DIY modification kit for a compatible factory GM engine harness, not a complete replacement engine wiring harness.
- Intended for installers experienced with automotive fuel-injection systems and engine wiring.
- VATS and other unneeded functions must still be removed from the PCM or ECM programming before the engine will run.
