Look on the electronics forum their is a pictorial STICKY on how to run the transducer cable for a HB on the Terrova it is really easy, I did it with mine takes about 5 minutes. Once done I epoxyed my cable right to the shaft and it worked perfect. Just epoxied every foot or so and wrapped with electrical tape for 24 hrs to let it dry. Slapped it together and away I went, NO problems at all. As far as the rest cant help you there sorry.
