This jumper harness allows you to use a 2012-2015 Civic Si engine harness and 2014-2015 ECU when swapping a K24z into a 2015-2019 Honda Fit.

**This kit requires completely repinning the ECU A connector so make sure that is something you are comfortable with!!


Parts you will need for the Civic Si setup:

  • 12-15 Civic Si engine harness & charge harness
  • 12-15 Civic Si OEM O2 sensor
  • 14-15 Civic Si engine computer  
  • 12-15 Civic Si Alternator 


You must make sure you use a ECU from a 2014-2015 Civic Si only. The 2014-2015 Si ECU uses push button start were the 2012-2013 ECU does not. 

You will need to check and verify
emissions rules and laws in your state for compatibility. These kits are intended for off-road use only.
