So what exactly are you needing done? Sounds like installing a 2nd battery & then a run to an anderson plug? Easy enough to do but it will take more than an hour unless you already have your interior apart. If you are running a 2nd battery, I strongly suggest hooking up a 2nd fuse box to run all your gadgets from. A run of 100amp cable from the 2nd battery to a 40amp circuit breaker then more 100amp to a new fuse block. From the fuse block you can then run what ever you like, eg, anderson plug, 12v sockets, extra lights. It's all very easy to do yourself if you want to & have the time. Just look around for dual battery set & rear fuse block installations on 4x4 forums & you will find all the info you need to do it all yourself.
