Introducing our Budget-Friendly K-Swap V3 Harness by CT Connects—built to deliver reliable plug-and-play performance at a lower cost. We’ve taken the proven design of our premium Carrot Top Tuning V3 harness and switched to more affordable materials, making this a perfect choice for those on a tighter budget. While the wires don’t have the same high-heat Teflon shielding as our top-tier option, they’re still rated for automotive use and give you a neat, clean look that easily beats old factory wiring.
Each harness is thoroughly bench-tested to ensure every pin is correct, so you won’t have to deal with the common connection issues found in other cheap harnesses. Every connector is clearly labeled with black heat-shrink and white text, taking the guesswork out of installation. Designed for 2002-2004 pinouts, this harness is ideal for K20 setups. If you’re running a K24, just swap to a K20 crank sensor or re-pin your existing connector to match.
If you run into any problems, our team is here to help. We can troubleshoot over the phone or you can send the harness back for a full test. This affordable harness puts you on the road to K-Swap success—without breaking the bank.
Note: You must use a K20 Knock Sensor, and CKP. Otherwise, you'd need to swap connectors, and repin the CKP as well as the KS. VTP connector is not included, and must be disabled in your tuning software.
