Who should purchase the Universal Harness?

The Hybrid Racing Universal K-Series Swap Conversion Wiring Harness is designed for those people who have decided to install a K-Series engine into a non-honda chassis or a chassis where a standard plug and play conversion harness is not available. (such as Preludes, DA Integras, Accords, and older Honda chassis)

This harness has also been used in custom open wheel cars such as the Ariel Atom, RCR Superlite Roadster, Sandrails, and 3 wheeled Trikes. It has also been used on Mini Coopers, Toyota MR-2s, Lotus Elises as well as full blown tubed frame race cars.

If your engine of choice is the K-Series motor and plan to use the OEM K-Series ECU than we can help you get it started.

What is included with the race harness?

The race harness includes a fuel pump relay, a main relay and a primary oxygen sensor relay. The harness comes wired with the provisions for the OEM K-Series 02-04 Wideband o2 sensor and an OBD2 port. This harness has outputs including, tachometer, speedometer, low oil pressure warning, malfunction indicator, fan control, fuel pump control and for the starter relay. You will need to supply the harness with a constant 12v and switch 12v source.

With over ten years of K-Series swap wiring experience, the Hybrid Racing Conversion Harness is the most widely used and reliable K-Swap conversion harness on the market. This conversion harnesses powers thousands of K-Swaps all over the world!

The K-Swap harness interfaces with your factory dash harness, your OEM K-Series engine harness and your K-Series ECU allowing for a simple plug and play K-Swap.

What engine harness does the Hybrid Racing conversion harness work with?

  • This harness works with all USDM / JDM 02-04 wiring harnesses including, K20A, K20A2, K20A3.
  • This harness is wired to use the factory wideband O2 sensor so European customers using the UKDM K20A/K20A2 wiring harness will need to convert the harness to use the narrowband type sensor.
  • This harness does NOT work with any 05-06 OR K24 engine wiring harnesses and ECU.
What type of connectors and pins do you use?

When we construct a Hybrid Racing harness we utilize brand new connectors, terminals and wire sourced from the same company that Honda utilizes for their connectors. These connectors are ordered in bulk from Japan and ensure that you get all new parts. In addition, all new connectors decrease the chance for errors in the harness as we do not solder any of the joints. Every harness is machine made and human checked so they are issue free.

What if I have questions or problems?

To ensure a trouble-free install all of the wires are labeled and neatly packaged. The most valuable thing you get when you purchase a Hybrid Racing harness is full tech support. This tech support extends beyond your harness and includes help with anything associate with your swap. If you have any problems at all with the swap just give us a call and a tech will get you the information you need. It’s like having a buddy down the street who has already done hundreds of K swaps!

Ball Launcher Poorly Made and Hard To Use, Save Your Money
This launcher was too long and thin to pick up the ball from the ground, I had to use my other hand to press down on it. The screw on handle was heavy and kept coming loose no matter how tight I made it, strain on the wrist to use. The ball holder end would often not let go of the ball when trying to launch it. I ended up putting it in the trash. I had two shorter Chuckit launchers that are much better made, will stick with them. I don't recommend this to anyone, save your money.

Go Get It!
GoSports does it again. Our family has a lot of GoSports products. It brings us comfort knowing when we order a product from them the quality is going to be great. The Ball Launcher is excellent. Our lab loves the soft tennis balls that come with it, preferring them over the harder rubber ones from other brands. The launcher itself is thoughtfully designed, well-made, and comfortable to hold. Our new go-to for daily fetch sessions.

Gave it a Try
I have always used the Chuck It ball and ball launcher. I thought I would try this since the price was better. There is definitely a reason it is priced lower. The handle on this one twists on and constantly comes undone when you throw, and it does not launch nearly as well. I would not order this product again.

A few usability issues
My dog is obsessed with playing fetch. It’s part of our daily routine. Pros - I like that this comes with two launchers so we can keep one at home and one in the car. - Build feels solid Cons - The cup is slightly too small for regular sized tennis balls. I buy the large Costco box of Penn tennis balls every couple of years for my dog. If you fully seat the ball in the cup/launching end, it’s extremely difficult to throw and puts some strain on your wrist. — the workaround is to only partially insert the ball when picking it up. - Like others have stated, the launcher does come unscrewed occasionally after a few throws. It’s kind of annoying so I’ll likely try some thread lock, but ideally that wouldn’t be necessary.

Fun!!!
I can’t say enough good things about this tennis ball launcher! Roxy absolutely loves it. Every time I pick it up, her tail goes crazy with excitement. It’s so easy on my arm, and I love that it gives her a great way to burn off energy. The launcher is sturdy, well-made, and works like a charm. If you have a high-energy pup like Roxy, this is a must-have!
