Using A Switch Pod Button For Message Centre Cycle Option

After I had conducted my Multimeter test yesterday to determine if those red wires I had soldered onto the Switch Pod individual button terminals were power wires I realized I needed to make a minor change to this other diagram I had done for an option of using one of the Switch Pod Buttons to cycle through the Message Centre messages. The Momentary Button on the Pod closes power to ground which energizes the magnetic coil of the Relay closing the Relay's internal switch and this then if hooked up as a switch between the GND and CYC should cycle the message on the Message Centre.
