Ktuned ECU Jumper Harness (05-06 to 02-04)

Applications: Convert a 2005-2006 K20Z1 harness to 2002-2004 K20A2 specs.  This ecu jumper works on K-swap vehicles only.  It does not work on the 05-06 RSX.

NOTE: A speed converter and/or rewiring of the VSS sensor may be required.

The best engine harness to have when doing a K-swap is the 02-04 K20A2 Type-S harness.  Until now, using the 05-06 K20Z1 wire harness for a swap was usually avoided because it isn’t compatible with a 02-04 KPro ecu.  Rewiring it isn’t much fun either, sitting in front of wiring diagrams trying to re-pin the Z1 harness to 02-04 specs.  Also, if you get one wire wrong it is not go to work, or worse you risk damaging the ecu itself.  That’s where our K-Tuned ecu jumper comes in.  It makes converting the Z1 harness to A2 specs 99% plug and play. There is only one simple wire to hook up and you’re done.  Now any 02-04 ecu can be used on your K-swapped car.
