I have it pluged into the fuse panel on an empty spot but it stays on all the time. I want it off unless I turn the key on like my radio. My radio fuse is right next to the blank that I plugged the depth finder in. why is one on and the other off when the key is off??
How do I hook this thing up so it does not kill my battery?
