transducer lead length

First request on this site. I have upgraded my system from ST60+ to the networking system when I installed our autopilot. I have purchased the itc5 modual and would like to use the st60+ transducers for depth and speed to intergrate into the system with a new multifunction display.

Question I have is can I shorten the transmitters lead length on the speed and depth transducers and hook into the ITC5 modual without effecting their function.

Thanks in advance.
