E30 K Series Swap Wiring Harness Adapter (K20, K24)
If you plan on swapping a K-series (K20 or K24) engine into your E30, our plug and play harness adapters are the easiest way to go. These work best with a 2002-2004 RSX harness. The ECU is intended to be placed in the E30 glovebox on LHD models or on the driver’s side on RHD models.
The original E30 gauges will function like normal. Additional information will be included with the instructions.
Harnesses include the OBD2 diagnostic port, wideband oxygen sensor connector, E30 temperature sensor connector, E30 c101 connector, K-series c101 connector, and the K-series ECU connector, along with 3 sockets for the main relay, o2 sensor relay, and fuel pump relay.
