Rywire K-Series Chassis Adapter

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 & cleanest.There will be 5 wires to be connected to your factory computer 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!

We also offer this jumper harness for the K powered Honda Insight. If you have a Insight, we will need your original Insight harness to borrow a couple connectors off of.

MADE IN U.S.A.

Attention Accord & Prelude Owners:

We may need to borrow your stock Prelude/Accord engine harness for reference of the shock tower configuration to complete your harness. This allows for the easy installation we are known for. Some models we have specs for, but the Prelude and Accord models vary so much that we would rather be 100% certain it's an exact match by having your harness to compare to.

1999-2006 Insight Owners:

We will need your stock OEM engine harness as a core. Please call or email us for more information before or after you have placed the order.
