The Demand Sensor / Throttle Position Sensor for the 1400's with throttle cables is under item number B044414. There's a rubber grommet/spacer that's needed but it doesn't come with a new Demand Sensor. The rubber grommet helps to secure the two throttle cables into the center of the Demand Sensor as well as keep out water and debris. I wasn't able to find this grommet in any of the parts books I looked at, 2014 to 2016 Cal Tourer and Eldorado.
Typically, the old one can be used. But, I'd rather have a new one on hand since I have a new Demand Sensor on hand. If you need one as well, the rubber grommet / 'Rubber Top' is under Aprilia part number: 854811 and retails for $3.46.
When mine comes in I'll post a picture of it and where it goes onto the Demand Sensor.
