Ferrite ring from humminbird

[hawgdog]

Anyone every installed a ferrite ring frm humminbird for interference issue?

Just wondering if someone has any pics. They sent directions, but i dont know the adapter cable from the universal sonar cable from my a?!?!?

The first pic is the directions they sent and the second is the cable on my boat where i "think" they are refering to.

Ive posted on the arkansas board and electronic board. Just wondering if anyone has installed one and possibly some pics...
