Ive searched quite a bit here and BBC, but wanted to get input from those that have done the same. Just ordered my structure scan from Three Rivers for my 2 HDS-7s. I want to install the unit in the starboard locker on the wall in front of the console. Thinking of taping into the accessory hot wire on the round A-10 panel. Havent looked under there yet, but what is the best way to tap into it – using one of those clips that you put in-line on the hot wire? Also, where to ground? I do a lot of mechanical work myself, but electrical always gives me pause, for some reason. Anyway, cant wait to have the structure scan, and I appreciate any input. Thanks guys.
