This wire harness connects your K-Series engine harness to your chassis interior harness while adding the E-plug and all its functions. This harness is primarily made for a K-Pro or Re-Flashed ECU but can be used with a stock RSX ECU provided you have bypassed the immobilizers accordingly.

This harness may require the user to pull the shock tower plugs into the interior for a better fit and cleaner installation. You are also required to drill a small hole in your exhaust tunnel for the O2 Sensor plug.

After a year of R&D, this method is the way our customers doing this swap said were the best & cleanest. There will be 5 wires to be connected to your factory ECU plugs with a diagram that accurately shows which wires to connect to. You won't use your stock engine harness with the K20, but you still continue to use your chassis Interior harness with this conversion, so don't toss it or cut it!

We also offer this jumper harness for the K powered Honda Insight. If you have a Insight, we will need your original Insight harness to borrow a couple connectors off of.

Loooove these shoes!
Size: 7.5 Wide, Color: Chestnut Brown Faux Leather
I have these in several colors, and they’ve become a true staple in my wardrobe. The Amazon Essentials Women's Belice Comfortable Slip-On Ballet Flats are exactly what I look for in an everyday shoe—simple, versatile, and comfortable right out of the box. The slip-on design makes them super convenient for busy days, and they pair effortlessly with everything from jeans to dresses to work outfits. They’re lightweight but still feel supportive enough for all-day wear, and I appreciate that they don’t require a break-in period. The fit is generally true to size, and the variety of colors makes it easy to stock up and rotate depending on the outfit. Overall, these are reliable, easy-to-wear flats that offer great value for the price. Not flashy, just consistently comfortable and practical—which is exactly why I keep coming back to them.

REALLY CUTE SHOE BUT CUT WAY TOO SMALL!
Size: 8, Color: Black Patent
I received the black patent leather shoes today and they are so cute! Sadly I need to return them because they are cut way too small. I normally wear a 7.5 or 8 on dress shoes so I ordered the 8. They are so tight across the top that it's uncomfortable as soon as I put them on. They are smaller than a normal size 8 dress shoe. The big toe area is extremely uncomfortable because it doesn't allow any room for it at all, so my big toe just presses against the side and end of the shoe without even walking in them. I have very narrow feet and these still are too small for me. So I am returning them and I already ordered a 8.5 W and hope that will fit much better. The patent leather is very cute and adds just enough dressy that I can wear them with slacks or my Capri jeans. I like the slip on and the cushion foot bed because it feels soft.
