Anyone want to share their wiring diagram for the trim coolie hat with Skyview AP panel. I have the Tosten CS grip that has a single common wire for every switch.

—————————-Edit—————————————

After looking back at the install manual, I understand the wiring for the trim. But, I’m curious about grounding the PTT in common with the trim on that single wire. Doesn’t that set up a ground loop? What kind of potential are on the trim switch signal wires going to the AP Panel?

My PMA 6000B audio panel ties all audio common back to the panel, including the low side of the PTT, via the mic audio low side of the mic jack.

Thanks in advance!

Should be 9 wires on the stick. The common wire (white) goes to ground. If you want to trim down when pushing forward on the hat and up when pushing back, the orange wire should go to pin 4 on the SV-AV-PANEL, and the black wire should go to pin 3. Reverse those if you want it to trim down when pulling back on the hat. Red wire to pin 10 and violet wire to pin 11. I can post a diagram later. Not able to do that right now.

Sorry. Just now noticed your edit.

It's a bias voltage, 4 to 5 volts if I recall, and it isn't an audio ground. It's unlikely to create a ground loop, but it wouldn't hurt to tie them both to your common ground if you want to be extra cautious. I usually do, but it likely isn't necessary. It isn't being routed with audio, so it can't induce noise from wire to wire.
