Description

The Rywire LHD EG/DC B Series OEM Replacement Engine Harness provides a direct replacement for the factory engine bay wiring in compatible vehicles. Designed for Left Hand Drive (LHD) EG and DC chassis, this harness is specifically tailored for B series engine swaps (96-01) in 1992-1995 USA model Civics and all models of 1994-2001 Integras. It aims to replicate the functionality of an OEM USA model Type R harness. Constructed with new connectors and materials, each connection is made using pneumatic heads for an OEM-quality crimp and is clearly identified with labels for straightforward installation. Heavy interference circuits are protected with proper wire covering, and the harnesses undergo 100% pin-to-pin quality testing and resistance checks to ensure reliable performance and prevent voltage fluctuations. This harness is ideal for applications using single-runner type intake manifolds. Important installation notes include the potential need to leave crankshaft and knock sensors disconnected if not used, and the necessity of utilizing the original donor "power cap" connector from the factory harness, typically an 8-position cap with yellow and black stripe wires, to provide power to the new harness. Note that this harness is for Left Hand Drive vehicles only and does not fit RHD configurations. It includes connectors for OBD2 96-01 distributor, alternator, and injectors, as well as sensors for air temp, oil pressure, crankshaft (if applicable for OBD1 ECU cars), knock sensor, idle motor, TPS, MAP sensor, purge solenoid, VTEC solenoid, VTEC pressure sensor, reverse light switch, water temp, starter motor, fan switch, thermostat ground ring, 4-wire O2 sensor, and speed sensor, along with passenger and driver side shock tower plugs.
