By popular demand we have made this specialty part available for purchase. This part is available for those of you who know exactly what you are looking for and just need a place to buy it. If you do not know what part you would need or how it is used, we strongly encourage you to purchase one of our complete plug-n-play conversions as we cannot supply any sort of guidance or support for this part.

    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.
