But if we use the RF connector with pigtails to test the ports, are you saying I would not need to remove the side panel?
The panel is just a circuit board with traces, a switch and an LED on it. It has no smarts.
The 2 Aux ports are wired in parallel, so a pigtail into the spare port allows you to remotely
monitor the comms on the Aux bus clock and data lines
for a piccy of how it is wired
If the handbox and wiring to the mount is OK, on booting you will see the clocking and data appear on the clock and data lines as the mount tests for any attached devices.
If your tech understands simple I2C comms, he can tell whats going on, ie if there is valid data there

PS, If using a pigtail, ensure the +12V line is insulated/covered to prevent accidents
you only need clock, data and ground
