Hybrid Racing K-Swap Electronics Package (Universal)

Intended for K-swapping a chassis where no plug & play conversion harness is available, our team put together this bundle that includes all the major wiring components for a trouble-free wiring install. This is suitable for any vehicle with a K20A/A2 engine, ranging from Honda and Acura (such as Preludes, DA Integras, Accords, and older Honda chassis) to full tube chassis race cars.

• The Rywire K-Series Budget Tucked Harness Version 2 engine wiring harness connects to your K20A/A2. Use with other engine models is possible but may require changing sensors or sensor connectors. 
• Hondata K-Pro V4 ECU provides tuning for your engine, and equally as important will overcome the factory immobilizer – a major hurdle for any K-swap. 
• A fresh Denso Wideband/Primary O2 Sensor is included to rule out any inconsistent data for a faulty sensor - your tuner will thank you later.  
• Hybrid Racing K-Series Swap Ground Kit will help avoid all kinds of headaches associated with poor grounding such as premature failure of electronics and faulty sensor readings.  

To tie everything together, we supply our own K-Series Swap Conversion Harness, a user-friendly harness that has been used in 1000’s of K-swaps worldwide. This allows the ECU to be connected to the engine harness, wideband o2 sensor, instrument cluster, and chassis wiring. By adding a constant and switched 12V source, the entire system will be powered and ready for action.   

Rywire harnesses are hard to match in terms of quality. They are made with all new materials including OEM quality connectors for a sure-fit. Every pin is pneumatically crimped, meaning if pulled, the wire itself will yield before the crimped connection fails. Harnesses are finished in expandable loom and connectors are labelled for ease of installation. All connections are 100% quality tested pin to pin. 

This particular Rywire V2 Tucked Harness caters to universal engine swaps as it routes more like the OEM K-series harness through the center or more to the right on the firewall. This makes it ideal for Right Hand Drive vehicles; however, it can still be used in LHD chassis applications.  

Hondata K-Pro V4 The K-Pro ECU is a specially modified 2002-2004 Honda ECU that allows connection to your laptop running Windows. The provided K-Pro ECU Manager software allows tuning such as: fuel/ignition trim, VTEC/VTC, adding flex-fuel for E85, monitoring of various inputs, and many other functions.  

Hondata ECU’s maintain factory form but allow you to get much more from your K-series. Provisions are included for outputs such as boost controls, flex-fuel, nitrous control, etc. In addition, data logging is available in the KManager software.   

ECU modifications are available with a send-in core for ECU numbers: PRB (A01-A12 & 305) PND (A01-A09) PNF PRA PRC (JDM DC5 Integra Type R) PRD PPA (A0#, A5#) PPL (A0#, A5#)

This Conversion Harness is made with connectors, terminals, and wire sourced from the same company that Honda uses for their harnesses. These parts are ordered in bulk from Japan and ensure you will get a brand-new product that will work perfectly with Rywire harness and Hondata ECU.  

Our Race Harness includes a fuel pump relay, a main relay, and a primary oxygen sensor relay. It comes wired with a provision for the included Denso Wideband/Primary o2 Sensor. This harness has outputs including: tachometer, speedometer, low oil pressure warning, malfunction indicator, fan control, fuel pump control, and starter relay.   

Hybrid Racing K-Series Swap Ground Kit 

Ground kits give you some extra slack when running ground wires so you don’t have to fool around with cutting and splicing to get everything connected.  Good ground connections are arguably the most important part of any electrical system. Without them, there's no way for current to flow. Being confident that your wiring is properly grounded is critical when it's time to troubleshoot problems with any fuel injected car. Obviously, this is even more important in the case of an engine swapped vehicle, where any number of electrical issues could arise. 

 A fresh wideband o2 is included to rule out any inconsistent data for a faulty sensor. This sensor plugs in via a connector in the Conversion Wiring Harness and interfaces with Hondata for critical tuning of AFRs.
