Product Details

Part Number: RY-K-ADAPTER-EK-LATE
Brand: Rywire

This adapter is made to allow the installation of a K-Series engine with the 02-04 K20 engine harness.
It will also work for our all our K-Series engine harnesses. K1 & K2 types!
  • This wire harness connects your K-Series engine harness to your chassis interior harness while adding the E-plug and all its functions. 
  • This harness is primarily made for a K-Pro or Re-Flashed ECU but can be used with a stock RSX ECU provided you have bypassed the immobilizers accordingly.
  • This harness may require the user to pull the shock tower plugs into the interior for a better fit and cleaner installation. 
  • You are also required to drill a small hole in your exhaust tunnel for the O2 Sensor plug.
  • After a year of R&D, this method is the way our customers doing this swap said were the best & cleanest. 
  • There will be 5 wires to be connected to your factory ECU plugs with a diagram that accurately shows which wires to connect to. 
  • You won't use your stock engine harness with the K20, but you still continue to use your chassis Interior harness with this conversion, so don't toss it or cut it!
