First problem I had with wiring up the MSE servo unit to drive the signal was that of power supply. My Accessory power bus on Summat Colliery is driven by a laptop psu and whacks out 18v DC, great for supplying CDU units but likely to fry the controller box that needs 12v DC.
Now, the MERG pulsed accessory decoder boards I use also have an option of an on-board 12v regulated supply to drive small steady state devices. These parts are optional in the build, but thankfully I saw fit to fit them "just in case". 5 minutes probing with a multimeter told me that I had 12v across the small capacitor next to the voltage regulator so two wires were soldered to either end of said cap and threaded through to the controller box
The controller box was screwed to the underside of the baseboard and wires were run from it to a switch on the Peco point solenoid (controlled by the MERG decoder) and power applied
Dynamis connected up and hey presto, fire the catch point and the servo does it's thing 😁 - now to fix the servo and connect it to the signal
