Sonar/GPS power connection question

[kaliona]

Going to install a new HDS-5 unit. With this sonar or any other unit for that matter, is it best to connect the power directly to the battery? I was looking at my switch panel that has toggle switches for the navigation lights, anchor light, blower, horn, and 3 more unused switches labeled "Accessory".

These switches are all fused and I'm wondering if I can just connect the power for the sonar/gps unit to one of the unused "accessory" switches. Running the power to the battery at the back of the boat is not a real big deal, but if I can use the existing switch, it is only about a foot away from where I'll be mounting the sonar/gps.

I wired mine directly to the aux battery but I did put an in-line toggle switch with an in-line fuse.

If you go to the battery put an inline fuse on the positive side. 3 amp.

You should be fine using the existing accessory switches and power. Just make sure the fuse is proper size for the unit you're installing. Not real familiar with the unit you're installing, but most sonar/gps units are not "power hogs" that would require low gauge wire run direct to battery, etc.
