88-91 CRX/Civic to K20

92-95 Civic/DelSol to K20

96-00 K-Series Conversion Harness

94-00 Integra to K20 Conversion

This wire harness connects your K-Series engine harness to the CRX/Civic/Integra interior harness while adding the E-plug and all its functions. This harness is made for a K-Pro or Re-Flashed ECU. (the stock RSX ECU's have immobilizers.)

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 (in some applications) with a diagram that accurately shows which wires to connect to.

You won't use your Engine harness with the K20, but you still continue to use your Interior harness with this conversion, so don't toss it!
