Rywire Chassis Adapter Harness (EK) Honda Civic K-Series 1999-2000

This adapter is made to allow the installation of a K-Series engine with the 2002-2004 K20 engine harness. It will also work for all our K-Series engine harnesses.

This wire harness connects your Rywire K-Series (Budget or Mil-Spec) 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!

MADE IN U.S.A.Notes:

- Rywire engine harness sold separately
- 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.
