Welcome, how can I help you today? No I would not try to re-use the old sensor as it will most likely not give you a correct reading. You need to use the sensors that are with the new control box. Every control box is designed to only work with certain other devices, like the topside and sensors if the wrong one is used the system will either not work or work incorrectly. The engineers have designed it to work with what they include.
Also it is never a good idea to splice wires together anyway. They never work correctly after that.
