MC Speaker to Bluetooth Switch

[AustinChopper]

Newbie here so forgive if I post in the wrong spot for this forum. I'm looking for some help to build the following setup for my motorcycle.

CURRENT: Sound system plays directly to stereo speakers in my fairing.
WANTED: To be able to redirect the signal from the speakers to a Bluetooth transmitter using a switch that can be mounted inside the fairing (switch accessible externally but guts inside). I think a 4pol switch would do that however I would like to add a small led indicator that would let me know the signal is set to the "Bluetooth side".

Is there such a thing as a 6 pol switch or would I need an 8 pol because I would want to separate the led ground from the speaker ground? (due to the power)

Any help would be appreciated ! Thanks .... Nelson
