JB4 Bluetooth Wireless Phone/Tablet Connect Kit Rev 3.7 (Separate Power Wire, N54 & pre-2017 JB4 systems only)

Wirelessly connect and control your JB4 with your phone!

This separate power wire is for BMW N54 systems and any JB4 system manufactured prior to 2017. All other systems use pinned power wire. Check board type below before ordering as most don’t use this adapter.

The JB4 Connect Kit (Rev 3.7) allows your Bluetooth 4.0 compatible iOS and Android devices to connect wirelessly to your JB4. View critical engine data in real-time, datalog, read codes, change maps, update settings, update firmware, and more, all from the palm of your hand! The REV3 mounts next to the JB4 in the engine bay eliminating the need to run a BMS DATA cable inside the cabin. It’s compatible with all JB4 products. Just plug it in to the JB4 where your BMS DATA cable connects, attach the power and ground wire to the JB4 harness using the included connectors, purchase the JB4 Mobile app, and you’re off and running. Please note the JB4 Mobile app is available for iPhone, iOS, or Android and sold separately via the Apple or Android app store on your phone. This adapter is not compatible with the JB4 windows interface.
