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. 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 Computer but can be used with a stock RSX Computer 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 &.
