Will this setup work?

I am wanting to make an animatronic for a Halloween project and through research I think I have the concept figured out as far as parts and hooking up. As shown I have a Polou Mini Maestro 12 channel controller powered by a 6v 3a power supply I will be connecting to the servo power pins. I will also connect the jumper to the two pins beside it to power both the board and servos from the same power source.
Next I will run single wire pins to the corresponding pins on servo channel 9 to power and control a PIR motion sensor. The next connection will be three sets of 3pin connectors running from channels 6-8 to 3 channels on a Cat 6 sender module. Via a 25 foot Cat 6 cable it will run to a Cat 6 receiver board connected to 2 Hs425BB Servos and a single HS65HB servo.
The final connection will be a single wire pin from the common ground pin near the USB port on the maestro to the ground on trigger 3 of the Sparkfun MP3 trigger, and a single wire pin to the servo ground pin on channel 1.

My overall goal is to have the servos run a sequence that alternates between audio tracks and the servos sync up to the specific audio and it will all be triggered via a motion sensor that will be set to allow the whole sequence to run before being able to be triggered again. So, is this pictured/described set up capable of doing this because I am completely new to all this.

Hello.

Most of those connections sound fine, but it looks like you are connecting the MP3 Trigger input to ground instead of the Maestro’s channel 1 signal output.

To clarify, the way the trigger inputs on the MP3 Trigger work, each input is pulled-high internally and driving one low triggers the specified track to play. You can configure channel 1 on the Maestro as an output (in the Channel Settings tab of the Maestro Control Center), which will allow you to toggle it between high and low. So, if you connect it to a trigger input (along with a common ground), you can have the signal be high normally, and briefly drive it low to trigger the desired track on the MP3 Trigger’s microSD card. Please note that the trigger input specifies the track by filename (i.e. trigger input TRIG01 tries to play the file name starting with 001). If you want to play more than one track, you can set up a separate Maestro pin for each trigger input.

ok thank you I will certainly try that.

Adding these photos to verify the wiring, just waiting on the power supply to arrive.

I see based on a post from a different user that I seem to have the wires crossed on my Spark Fun MP3 board. So I will flip that.
