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.

For the DIY'er who wants to convert their 4" MyFord System with SYNC to the 8" SYNC 2 or SYNC 3 system. This harness only supports USB Media hubs with the 4 pin connector. Includes connection to ACM to support SiriusXM Travel Link. Please note, this is for advanced users and requires many additional parts and programming.
