Exposed Rear OK?


I am installing four 12 volt batteries for a new motor in my boat. What size battery cables do I need to hook these in series?

Also, I am looking at boat switches from your partner site, EzAcDc, however I need to know if they snap into a the console panel, or do they need a box to be mounted into? If a box is needed do you know where to find them?

Thank youEzAcDc offers a excellent selection of electrical products for your boat wiring project


Hi James,

The best way to determine the cable size is to use my boat wiring size calculator. Use the entire run as your cable length to calculate the correct wire size.

Our boat switches snap into a hole that measures .85″ x 1.45″. If the rear of the panel is completely exposed, I would recommend some form of protective cover. If used for DC, there is no requirement for a safety enclosure.

Hope this helps,


Bass Boat Wiring


I have a 1989 Bass Tracker Pro 17′ bass boat and need help with the boat wiring.

I keep blowing fuses. The fuse panel became wet a year ago along with all of the wires, the boat almost sank in a very bad storm which left two feet of water in the boat, everything got wet. Bass Tracker

I have traced wire after wire and have decided after wasting hours time that the panel might need to be replaced?? I can not find a boat wiring diagram for this boat anywhere on the net. I’ve replaced a couple of switches and bought a lot of wire and hours of time has been spent re-wiring on thing at a time without any solutions.

I’m considering one of the panel rewire kits from EzAcDc.

I have heard that you helped to design this system…can you tell me if it’s going to fix everyhting for me?


Hi Caroline,

The switch panel rewire kit will provide you with a new fuse block and all new wiring – but only for your boat’s switch panel. But, if you combine this with an EzAcDc boat wiring harness, you will have replaced all of the accessory wiring on your boat.

The harness is sold in several different configurations. By far the easiest to install is the “snap together” version. It is plug compatible with all of the new wiring on your switch panel, so it goes in very quickly.

And, if you would like to replace all of your switches, our partners at Ez have a complete switch kit that will easily connect to the rewire kit.

Hope this helps.

Please let me know if you have any questions,
