HELP
This is the third radio I've tried and troubleshooting points to a bad radio, but I'm not convinced. 2014 F150 xlt radio speakers were crackling when using the voice activation for blue tooth. The music would only come out of one speaker. I replace the radio with a cheap Amazon all in one and no sound. Found the harness wasn't pinned correctly so I got another one, but upgraded to a Jensen J1CA7 and Crux SOOFD-27C harness with CAN module. No sound output. Now I have a JVC KW-M180BT and still no sound. Radio powers up with ignition and Bluetooth connects. No radio no Bluetooth sound and no usb connected sound. I probed each speaker wire at the Crux harness with a 9v battery and they all pop. What am I missing!?

From the back of the ford harn. No connection to the Crux on that small yellow/green wire.

From the back of the Crux. No wire for the little yellow/green wire.

Back of the ford harn.

Back of the Crux. Only 2 wires used.

Not sure what this does.

Was your old factory unit with the 4.3 screen? I think it was. Crutchfield says that harness won't work. I used iDataLink on my old 2014 XLT with the 4.3. That worked
