Here are the switching options for the 6165 pedal, some listed officially by Ernie Ball - some not!!
The tests were conducted using a JP6 with Piezo, a Hardtail Albert Lee SSS with no Piezo, an EB 6165 pedal, AER acoustic amp and Blues Junior tube amp.
1.
Mono leads out from guitar
Mono/Piezo (As described on the Pre amp of the guitar) output into Input A of the pedal.
Stereo/Mags output of the guitar into Input B of pedal
Mono leads out of pedal
Output A sending Piezo to AER
Output B sending Mags to Tube amp.
2.
Stereo Lead from guitar output marked Stereo/Mag into Input B of the Pedal
Mono leads out of pedal
Output A sending Piezo to AER
Output B sending Mags to Tube amp.
Both the above options will allow you to pan between the two amps, or control volume of the two amps in tandem, depending on the toe switch selection. (Two toe switch selections only)
3.
This test was conducted using the same amps but using an Albert Lee Hardtail with no Piezo
Mono output from guitar into Input A of Pedal
Mono leads out of pedal
Output A sending signal (magnetics) to AER
Output B sending same signal (magnetics) to Tube amp.
This option 3 will allow you to pan the magnetic signal between the two amps, or control volume of the two amps in tandem, depending on the toe switch selection.
I have used this option to run a tube amp and a voice box (an amp converted to be a voice box. Just imagine you are playing e.g. Framptons "show me the way". You can merrily play the song through the tube amp. When it comes to the voice box bit, the pedal will now switch the signal just to the voice box, and of course back again to complete the song)
Here's where it gets weird and thanks to Beej for "seeing" this.

Plugging the JP6 guitar into the A + B Outputs of the Pedal, then running the one amp using a lead from Input A of the pedal, will pan between the mag and piezo into the one amp. Great for hands free switching between the Piezo and the mags. Remember, the JP6 has a toggle switch to do that - The Albert Lee /silo/ Axis does not have a toggle and you would normally have to rely on controlling the mags and Piezo with the separate volume controls.
the same effect can be obtained by:-

Stereo Lead from Stereo/Mags output of guitar into the Output B of the pedal
Mono lead from Input A of the pedal to the amp works the same as above.
Here's a few old video clips that also help to explain.
If you come across another permutation, then let us know?

and here's one of the mono Albert split between two separate amps

here's a bit of info from Beej regarding buffered stereo and mono outputs ... ...
The mono output on the JP gives you a buffered combination of mags and piezo, while the stereo output gives you both a passive mag signal and a buffered piezo signal.
Some people like the passive output from the mags better and prefer to load their signal a bit rather than having a buffer right at the start. Then again, some people like the opposite ...
you can't simply connect the T and R of the stereo cable because of the different impedances. You need to buffer the signals before you mix them, either through the onboard electronics (using the mono output) or an external mixer (using two separate signals).
