A while back, we extolled the benefits of a Honda K-Series engine swap. And if that sufficiently whetted your appetite to start your own project, then we’ve got good news.

The Honda tuning experts at Hybrid Performance have developed a series of swap-specific parts to eliminate a lot of the hassles associated with a Honda K-Series (including the K20 and the K24) engine swap. Here is some of the swap stuff that caught our eye.

Hybrid Racing K-Series Swap Conversion Wiring Harnesses

Nothing can be more frustrating than retrofitting a swap harness, which is why Hybrid Racing offers a range of plug-and-play harnesses. They connect directly into your car’s OEM dash harness, K-Series engine harness, and K-Series ECU, so that they’re all able to communicate seamlessly with one another. Not only does this eliminate a lot of tedious cutting and splicing, it means your dash gauges will function as if the K-Series engine was installed at the factory.

Hybrid Racing uses precision machines to make each harness, and they feature brand new connectors, terminals, and wire sourced directly from Honda’s OE supplier. In other words, it’ll be a perfect match for the one you’ve already got.

Perhaps more importantly, this module disables multiplex code P0600 so the ECU will run error-free. It’s compatible with OEM 2002-04 Honda/Acura ECUs with PLM, PLR, PND, PNF, PRA, PRB, and PPA model codes. Click here for more details.
