Trim with SV-AP-PANEL vs VP-X sanity check

[Riseric]

Hi all, I'm almost finished wiring a RV-8.
Skyview HDX, pitch and roll servos, Ray Allen Pitch Trim.
Sanity check for me concerning Trim wiring.

Not having at that time received the Dynon Skyview goodies, I initially connected the Ray Allen Pitch Trim 5 wires and the trim switches to VP-X as per their instructions.
I now realise that I will need to re-wire the Trim motor and the Trim switches if I want to enjoy the Auto-Trim along with the Auto-Pilot through the SV-AP-PANEL.

If I understand correctly, it would be necessary to entirely un-plug the Trim motor and Trim switches from the VP-X, then connect to the SV-AP-PANEL D15:
the 2 white wires of the Trim motor to #7 & 8,
a 12V 4A (from VP-X) to #9,
a ground to #2,
the pilot's and copilot's Trim switches to #3-4-5-6 as per instructions?

Also the Pitch Trim motor's 2.5V, ground and position input to the EMS?

I believe I'm understanding this out correctly, but before I start to un-do stuff, I'd like to confirm with people that have the same set-up.
Thanks !!!

You might consider a switch that swaps between the two. If the AP Panel fails, it is supposed to allow pass-through trim control but, if that also fails, a flip of the switch would allow control via the VP-X.

Thanks Raymo for your suggestion, is that something you did? With a DPDT switch?
I feel ok with the bypass if the AP Panel fails, I prefer a simple setup.
If all fails, well I guess I'll fly without the trim and land ASAP...

I don't have a VP-X in my system but would install a power-kill or pitch trim reversing switch, if/when I re-build my panel for IFR. The AP Panel will stop trim input after 3 seconds but, IMO, that is too long a period. In flight trim inputs are typically sub-second.
