IMHO, your best bet is to just buy a cheap (or not) fishfinder for the depth instrument, and a cheap (or not) GPS for the speed.
The transducers you have are shot. There must be a reason the PO cut the wires. Instead of wasting your time trying to find that out, either install new transducers if you really want to use those old fashioned instruments.
The cheapest fish finders are about $100, and that will include a transducer than you can mount INSIDE the boat (assuming you have a solid fiberglass hull). You can get a cheap GPS for about the same. For $350 or so, you can get a 3.5" color chartplotter / fishfinder. That will give you WAY more information than a digital depth meter and knot / log.
Yes, I know the GPS provides SOG and the knot / log provides STW.
