Default Trouble installing Bluetooth on Older JB4 Box - 02-23-2019, 11:48 AM

Hello,

I have an older version of the JB4 box. I am trying to install my bluetooth adaptor, but I am not certain which color wire to tap for the power cable.
In all the installation videos of the bluetooth performed on newer JB4 boxes, they tap a red wire. Do I need to tap a red wire as well for the older JB4?

Thanks,

Either red wire in the JB4's main DB25 loom should be fine to tap into.

Thanks! Now if only I hadn't dropped half of my wire tap into the engine bay

Disable BT and wifi, restart device, enable BT, try again.

Check Connect Kit installation. Ensure positap is making a solid connection and that the DB9 connector is secured. Verify the voltage at the positap using a multimeter. Ensure the Connect Kit is as far away from nearby batteries/metals as possible as that can cause interference.

See if a "JB4" device appears in your Android device's Bluetooth menu.
