Our 4″ to 8″ Harness “B” is a harness that can be used to upgrade a number of vehicles, like the C-MAX, Kuga, Escape, B-MAX, Fiesta, Transit, Transit Connect, and more.

We also offer FREE programming files with your purchase, something no other online store does. This allows you to get up and running quickly using an OBDII dongle, without messing around with a bunch of settings or hex codes in FORScan.

Please feel free to check out our Guides tab for more information on what other hardware you’ll need to complete your upgrade.

We pride ourselves in providing the most value out of any online store when it comes to Sync 3 Upgrades.
