Swapping a K-Series engine into a Honda Civic requires a lot of parts and knowledge.

Some parts are easy as pie, others can get quite overwhelming.

The electrical topic is probably the most complicated one when it comes to a 01-05 Honda Civic K-Swap.

Indeed, it is not as simple as installing some aftermarket engine mounts or changing the shifting cables. But with good guidance, it's possible to achieve the goal of a properly running engine without any error codes and malfunctions.

Besides the fact that there is not much information available on this topic, the few helpful websites and blog posts are very specific and contain only information chunks - there's no clear path which describes you what exactly has to be modified.

While we were working on our second Civic K-Swap project, we decided to create a guide that contains all the information you need. The entire job can be quite overwhelming, especially for someone who's not so familiar with car tech.

That's the reason why we invested hours of work and effort to come up with an accurate and easy understandable step-by-step guidance which supports you throughout the whole book. A lot of photo material adds even more value.

Enough with talking. You probably can't wait to get one of these guides in your hands, right? The guide is available as an e-book so you'll get instant access!


The 01-05 Civic K-Swap Wiring Guide explains you exactly how to modify the K-Series engine harness as well as how to wire in the primary oxygen sensor for proper operation without any error codes.


We'll give you exact guidance on how to re-pin the engine harness so that the car can communicate with the K20 engine.

In order to get the primary oxygen sensor working, there are different approaches depending on the type of ECU and year of your Civic EM2.

We'll show you how to wire in the sensor in combination with a PRA (Civic Type-R) or PRB (Acura RSX) engine control unit.
