    4D is amazing to deal with. I ordered this product it arrived In a few days. During installation I had a few questions that they helped me with. They were awesome!!! I would recommend them with 5Stars

    The wiring harness makes the install so simple and easy. I tried to do the re-pinning myself and could not get it to work and so i put everything back to original and got this harness. As soon as I installed and ran the programming it was perfect. Immediate success. Took me 30 minutes.

    Fast shipping

    Posted by Perez on Apr 11th 2020

    Shipping was super fast. Ordered on Thursday and I received it on Saturday.
    My only complaint would be not knowing if the harness included the 2 USB cables as your YouTube videos showed that they did. If I would have known I would have ordered them as well to everything in at the same time.
    Thanks for the product.

    Cable works

    Posted by Kason on Oct 3rd 2019

    This is a solid piece of work. You need much more than just this cable to make this work, so I would recommend their kit, but if you know what you're doing or can do a lot of research, then this cable pays for itself big time.
