2002 Supra Launch - Need to replace Tranducer

The previous owner ripped all of the wiring from the transducer out of the boat. Know idea why.

The transducer says Airmar on it, but not the model number. It looks like the DTS800, can anyone confirm that this is the right model?

Any other advice on how to get this thing hooked back up and working would also be appreciated.

I have a 2002 Launch and am ordering just the spindle wheel for the transducer. Pretty sure its a Airmar ST300.

Thank you. Question, that model only does speed and temp, but not depth. Where is the depth located then if its not in this unit?
