Rywire Honda B-Series OBD1 Tuck Budget Engine Harness w/Chassis Specific Adapter

If you're tucking your engine bay on a Honda Civic EG or Integra DC2 with a B or D-series engine and an OBD1 ECU, this Rywire engine harness is built to make that clean look a reality. This harness is designed to route your wiring neatly behind the engine or firewall, keeping it out of sight for that show-car finish. It's a budget-friendly option that still gives you the core functionality you need for a tidy engine bay.

Rywire is well-known for making harnesses that simplify complex wiring jobs, and this one is no exception. It's constructed with high-temperature TXL wire, which is standard in the automotive industry for its durability and resistance to heat and abrasion. The harness comes with a chassis-specific adapter for the Integra 2-pin (2B) connector, meaning it's made to plug directly into your car's factory wiring without needing to cut or splice into the main chassis harness. This makes installation much more straightforward and reduces the risk of errors.

What's included is the engine harness itself, along with the necessary chassis adapter. This setup is designed to work with OBD1 Honda ECUs, which are popular for their tuning capabilities. While this is their 'budget' version, it still carries the Rywire reputation for well-built components. You'll want to ensure you have the correct ECU and any other supporting modifications in place for your B or D-series swap before installing this harness.
