I have a 2021 919 and am having livescope installed soon. The guy installing has recommended a sea clear power harness. With my boat already having the Integrated Wiring (I believe thats what its called) is there a need for a Sea Clear Harness?
Any advantage at all? I would like to not spend $450 if its not needed but I do want the best imaging possible.
I will be running a Garmin 106sv and a helix 10 at the bow and eventually just one helix 12 at the console.
