This Custom DC harness comes witha Battery, and Trail tech voltage regulator.  This is a complete DC kit for your Blaster Kit comes with custom harness, Trail Tech regulator and an 1.3 amp hour sealed lead acid battery. The battery is not intended to be used for reserve capacity. It is there to act as a capactitor to smooth out  voltage peaks. My harnesses are very well built, just look at the pictures and you will see the quality. I use very good wire, much better than OEM even, see video below.  The battery wires are long enough to allow you to place it in your tool box under the seat. A small notch will need to be cut for the battery to fit. The cut is inside the compartment. 
If you would like this harness built for a different year, just put that in your buyer note. I don't have those listed just yet but am happy to build it for you.  This is a great setup because you are not tied to the battery or regulator. The regulator is name brand and has a warranty of one year, it's not some china one you'll never find again. The battery is also very common and easy to find. Being the two are separate, you can always upgrade or change your battery in the future with no worries.
