Everything You Need to Wire Your K-Swap in One Package
You've got the K20 or K24 ready to go into your Civic or Integra.
Now comes the part that stops a lot of K-swaps in their tracks:
The wiring.
Which engine harness do you need? How does the K-Series ECU connect to an older Honda chassis? How do you get your factory gauges working? Which ECU should you use? And once it's wired, what calibration are you supposed to start the engine with?
We've put together a complete package that takes the guesswork out of it.
The Kugan Tuning K20/K24 K-Swap ECU & Wiring Package combines a Hondata KPro ECU, Rywire K-Series Engine Harness, Rywire Chassis Harness, and a FREE Kugan Tuning custom basemap into one complete solution.
Install it correctly, load your basemap, turn the key, and get your K-swap running.

This package is available for:
1992–1995 Honda Civic

What's Included
1. Rywire K-Series Budget Tucked Engine Harness
A clean, purpose-built K-Series engine harness designed to eliminate the mess and confusion of modifying old factory wiring.
The harness connects your K20/K24 engine sensors and components to your ECU while providing a clean, tucked appearance in the engine bay.
Perfect for street cars, turbo builds, all-motor setups, drag cars, and clean engine-bay builds.
2. Rywire K-Swap Chassis Harness
This is what brings your K-Series drivetrain and original Honda chassis together.
The Rywire chassis harness provides the necessary integration so important factory functions can continue to operate properly, including compatible:
Tachometer / RPM
Vehicle speed / MPH
Coolant temperature gauge
Starting and charging functions
Other required chassis connections
Instead of trying to decipher wiring diagrams and splice multiple factory harnesses together, you get a purpose-built solution designed specifically for the swap.
3. Hondata KPro K-Swap ECU
At the center of the package is a Hondata KPro-equipped K-Series ECU, giving you one of the most proven Honda tuning platforms available.
KPro gives your tuner control over critical engine parameters and strategies for naturally aspirated, turbocharged, supercharged, and other performance K-Series combinations.
Your ECU also includes a 1-Year VIP Warranty from the date of purchase.
4. FREE Custom Kugan Tuning Basemap
Buying the parts is only half the battle.
You still need a calibration that matches your engine.
That's why this package includes a FREE Kugan Tuning basemap built around the information you provide for your specific setup.
We'll account for modifications such as:
K20 or K24 engine combination
Intake
Header
Exhaust
Injector size
MAP sensor
Naturally aspirated or boosted configuration
Other relevant engine modifications
This gives you a much better starting point than simply loading a random calibration from the internet.
For the easiest initial startup and basemap process, we highly recommend using OEM K20/K24 injectors when appropriate for your combination.
A basemap is intended as a starting calibration and is not a replacement for a completed dyno or remote tune.

Installation Is Straightforward — But Grounds Matter
Although this package is designed to dramatically simplify your K-swap wiring, installation still needs to be performed correctly.
IMPORTANT: Make sure the engine-harness ground is securely attached to a clean, bare-metal grounding location on the engine.
Poor grounds can cause no-start conditions, sensor problems, charging issues, ECU communication problems, and other electrical problems.
Follow all supplied installation instructions and verify your connections before attempting to start the vehicle.
