You can replace the
"Akra Flower Pot" pipe with the
"Akra Wireless Kit" pipe, because these pieces are interchangeable.

However, the butterfly valve requires wiring to function: creating a required vacuum upon start up (even with the wireless kit, upon cold start you'll experience an inevitable 2 to 3 second noise that subsequently dies away as the system automatically goes into closed valve mode) + toggling between opening and closing the butterfly valve.
Do yourself a favor and back order the wireless kit to have peace of mind. Your neighbors might not gonna appreciate cold starts with a race sound rumble which you can't quiet down. It is loud.
