Trying to connect Humminbird 197c to existing Garmin 160c wiring transducer

Greetings. I can't find a wiring diagram that shows what pins on the Garmin Side are for the existing Garmin transducer. Or for the humminbird either. Here are the pics of each The round one is the Garmin. I figured out the power but there are too many combinations for the transducer. the one with the tape has the power wires figured out. Thanks

While both units are dual frequency, they use different frequencies.
Transducer and head are not comparable

thanks. I could still use the wiring diagram because if I put the humminbird transducer in I may use existing wiring . What transducer do i need?

Just google transducer for 197c or 160c looks like 60 some bucks for either one.

no, your new transducer will have new wiring. simply pull out the old wiring with the old transducer and use that to pull a section of cord thru. then use the cord to pull the new transducer wiring thru.
