Installing VPX with my Dynon HDX and dynon autopilot servos and Dynon autopilot panel. I've wired the pitch trim power through the autopilot panel, but the pitch trim sensor info back to the VPX which feeds the HDX. I don't have my wings on yet, so the roll servo isn't connected yet. I'm hoping that's my problem and this will resolve itself when I do. But for now, my pitch servo isn't responding to the hat switch on my stick. Before I go diving under the panel and fight wires, I'm hoping someone might have some insight for me. Thanks.

Did u do a system Configure to ‘ allow’ control of the servo ?

That was a quick find, not always easy to troubleshoot ‘issues’. Was that on an RV14 ?

Thought so re 14 - FWIW, I never use those ‘cheap’ connectors & prefer dsub connectors for more essential to flight equipment like a/pilot servos & trim systems YMMV.
ps - I have a customer who insisted on replacing the supplied wiring loom & replaced it with a straight through system eliminating unnecessary cheap connectors for the very reason you had a problem with yours.
