Setting up your Sprinter van’s electrical system is a daunting experience that requires a lot of forward-thinking and in order to be successful, you need an wiring diagram for your van. Also, breaking down the electrical build into sever steps will help make things easier for us DIYers! Â
The first step I recommend to start with is determining all of your appliances and electrical components that you will use in your van. This will not only help you understand what size battery bank you will need but it will also help you plan what gauge size wiring you need. Once you concluded what you want in your van, the next step is to create a wiring diagram. You can find my wiring diagram below as a reference. After you have your wiring diagram created you can use that to get measure how long you expect the wires to be. From here, you’re ready to order your wiring and get started running your wires.
Disclaimer: I am not a certified electrician and by no means an expert in van electricity, however, this post below showcases how we set up our van’s electrical system.
Kevin,
Curios as to why you designed with two grey water tanks?
Understand you have two water valves for drainage. Was this to balance weight distribution?
Seems like you could have combined them into one tank.

Yes, we designed it that way for weight distribution and so we could install the tanks right under the appropriate area (sink, shower) rather then finding a larger area under the van to install and needing to run additional plumbing.
