Maybe I missed something, but it looked to me like a single wire with a female plug that went directly into back of dept finder, then one wire split to the transducer on bottom of TM and the other went through the little hole toward back of boat. So I guess the new transducer comes with both wire and I use the existing one to pull the new one back to power supply? thanks Last edited by zoomCatD6R on January 30th, 2013, 12:29 am, edited 1 time in total.
