I have a Lowrance 3400 that hasn't worked for a long time. I have a new 3500 that should use the same transducer, assuming the transducer is still functional. The 3500 has a gray connector on the back. The 3400 has no connector on the back of the unit: the heavy black wire comes out of the unit and disappears into the bowels of the dash.
Anyone know if there's a gray connector in the line anywhere on the 3400s?
