Help, with HUmminbird Transducer!

[lp59]

I have a 1998 Bass Boat that has a Humminbird XNT 14 74 T transducer epoxied into the hull. It works great with the Onix that I sold to my nephew. I now have a Helix 10 MSI and a Helix 5. The Humminbird XNT 14 74 T is under the gas tank with no way to remove it without completely dismantling the gas tank, batteries etc. (we would have to remove everything from the gas/battery compartment.). There is no other place for such an in-hull transducer. Can I wire a helix pigtail to this transducer. (I have a pigtail and journeyman low voltage electrical experience & knowledge). Can you please give me the wire color hook up information. The wire colors in the cable are Yellow, brown, black paired with a Black with a White stripe in its own foil Sheild. There is an overall foil shield and bare drain wire. Thank you Dave
