    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, and 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 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 associated 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!

These work
Size: 2 pairs black L
My husband loves these they help his very dry feet. As others have stated they are extremely difficult to walk in so have to be careful but they do work nicely.

Potential Fall Risk
Size: 2 pairs black L
While these socks do indeed help soften rough skin on your feet, there is a risk of falling while wearing them. Although they have treads on the bottom, which would indicate they’re safe to wear with nothing else, when you put moisturizer on and then wear them your foot can slip inside the sock . This causes you to lose your balance and fall, which happened to me. I’ve thrown them out.

I could be a foot model now!!!
Size: 1 pair black L
I wear work boots almost all of the time so I bought these to put on my feet with salycylic acid to moisturize and try to get rid of a stubborn corn on the ball of my foot. It helped drastically after a few nights of lounging in the house with them on.

Best Card in My Wallet!
Having this card from Prime/ Sync has made things so much easier ! I order something & then go to cart & pay with my Prime card, nothing more. I don’t need to worry about theft or further actions or delays. It’s a done deal & I have more time added to make an additional purchase if I need to in case I forget something. I love this card 💞. So easy, I buy more here cause it’s faster, safer, & all in one easy step & Amazon has just about everything there is so why not ? Best card in my wallet !!!

2026 it has saved me
I never wanted a store card only! When I first applied I was bummed that I only got the store card and I thought about canceling it. BUT A lot has changed this year for sure. New grandparents, grocery being so EXPENSIVE and everything in our house as far as electronics needed to be replaced. Very easy to apply for, love the fact that you can apply without getting a hit on your credit and if you want to accept the offer then do so and if you decide that it’s not enough credit then you can decline the offer and no hit to your credit. I will say this, this was the lowest card that I was offered but I chose to get it anyway and within a month I had already received a credit line increase. I also took a trip out of the country and was able to order stuff and have it delivered with no problems. Every time I use it I get cash back and am able to use that on my next order. This is my weekly card for groceries. I definitely can’t wait until it upgrades to the visa, I would definitely get more use out of it. For those who are Amazon shoppers, it’s well worth it. So far so good, Good Choice.
