I just designated my bottom transducer "R" and top "L" but the cable does suck. The pinouts are kind of ghetto, at least the way they made the cable. I PM'd toddr about it and he was not interested in making one, as i have no desire to make cables anymore. Nick and i are searching for the right cable, and i am waiting to hear from SP about pinouts for a 2 cable "Y". After heavy use the stock cable will fail, no doubt about it.
