Aladdin System

I'm changing out my tank sensors to the SeeLevel system. Does anyone know where the current wiring is?? Color location etc. I would like to use one of the existing wires instead of running a new one thru the coach. Everything is run thru the Aladdin system and I do not have the separate display head as seen in the videos. (That would be too easy) I've removed the panels in the wet bay and found 3 round gizmos that are attached to the bottom of the tanks but there appears to be phone wires attached to them. Pic below. I don't like to assume and start clipping wires that aren't supposed to be clipped. If anyone knows, your help would be greatly appreciated. Thanks...Dennis
