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.

Pups all time FAVORITE!
Color: Dim Sum Dumpling Pet Toy Set
Our pups FAVORITE “ball”. He’s obsessed and has a blast with these little dumplings. Small size toy, but our medium labradoodle loooves them. Not to loud of an squaek either. They last quite awhile before he pops the squeaker. Fabric holds up really well.

Great squeaky fetch toy for small dogs
Color: Dim Sum Dumpling Pet Toy Set
My dog loves these little squeaky dumpling toys. They are the right size for small dogs (under 20 pounds) to chase and fetch, and they have good squeakers inside. They have a friendly look and my dog can fit them in her mouth.

Cute toy and well made
These are very cute and so far my dog has not destroyed them and he’s a very aggressive chewer. They are great quality. The colors are vibrant. Rocky loves the squeaker. They're light weight and the perfect size . He enjoys playing with them. We like to take them when he’s not looking and throw them to watch him go fetch them.

Love these!!
My dog absolutely loves these toys!! I’m grateful they don’t tear up easily because he’s really harsh on toys. Love that you can add treats or a water bottle to get more engagement and enjoyment. This by far is one of my dogs favorite toys. Great value for the money and great quality.
