Purchased and installed a XP-14-20-T (710248-1) in hull for my onix. Also purchased a AS 14 SI DBY sonar splitter cable for Onix units p/n 720083-1, Now here is the problem, the transducer end is not the same as the splitter end. Do I need another adapter? Its an Onix 10 si. Trying to run both in hull (hi speed)and the si transducers. I have already epoxied the in hull transducer.
