Electrical System Installation


We’re very proud to present you the electrical system installation of our Ford Transit DIY camper van conversion!


This post is a collection of images of the installation process.


For everything related to the design process, we recommend you to read the post “Electrical System Design”.

Electrical System Design




(We honestly don’t know the exact hours; there was so much work performed here and there, some things were completed later, some things were improved, etc. Needless to say, this is an approximation!)


TOTAL COST : ~2000$ USD (this excludes the solar panels installation)

We used mostly marine grade material as it is the highest quality available. We don’t want to mess with safety or long-term reliability; the electrical system is not the place to cheap out…

We won’t go in details for the material that follows, because it varies from one electrical system to another. For example, if your cable length is different than ours then the diameter will be different than ours. So will be your terminal rings diameter and quantities, etc… Do your homework! And check our Electrical System Design post for more info.









We’re not electricians. What we present here is the result of countless hours of research through the interwebs and through knowledgeable people that did it before us. There might be mistakes in our diagram, so make sure you fully understand what you are doing…



First of all, the location of every major component was determined to minimize the space occupied by the installation. The 3D model layout was very handy for this task.

But most important, we followed our detailed diagram to assemble everything together. We don’t think we could have made it without the diagram…

There are just too many steps and details to cover everything, so what follows is some pictures of the installation process. If you wish to see specific stuff, you can always request it in the comments section!

Passive heat management: cool air enter the side of the cabinet (from the “garage” side), then escape through a large gap behind the drawers and through an opening we left on the side of the cabinet.



Removing the drawers will give us the access to the electrical system


Inverter Van Battery Positive

The inverter is connected to the auxiliary positive terminal under the driver seat. It is protected with a 200A Class-T fuse.


Van Batteries Cover

The inverter connection is contained within the batteries cover. Nice & Clean.



We did that!





  • We added a remote to the inverter, because sometimes (alright, most of the time) we forget to turn it on before driving to charge the battery. Here is the remote: http://amzn.to/2hLJBjU

  • We decided to minimize the electrical cables length, so we don’t have a sexy distribution panel to display our switches. The switches are a bit hard to access, it might irritate us in the future. We’ll see.

First month on the road review: 

(The following text is extracted from faroutride.com/first-month/)

No surprises here, it’s going as planned. The battery state-of-charge (SOC) normally doesn’t get below 80% and is getting charged almost exclusively by our solar panels, except when there are a few days of bad weather then we top up the battery via the alternator. As we mentioned a few times, we would install a Sterling Battery-to-Battery charger (http://amzn.to/2xmHZ6W) if we had to do it over (so we don’t have to think of charging the battery from the alternator, it’s all automatic with the Sterling charger). Winter will be the real test for our electrical system, so more to come…

Hello! We’re Isabelle and Antoine, a couple dreaming of being on the move and we’re seeking for the ride of our life. We bought a Ford Transit van, converted it to a campervan, sold our house, quit our jobs and hit the road full-time to make our dream a reality. We are sharing this in hope of inspiring and helping others to follow their dreams too!

    Hi, I’m interested in knowing how you wired up the 110 AC ground and neutral of the inverter and the shore power battery charger. Are the AC grounds connected to the vehicle chassis? Does the inverter bond the neutral and ground together internally?

    You’ve created an amazing website here! I love the style, the photos, writeups, graphics, etc. It’s informative AND a treat to look at.

      Terri, i wish you did not brought up that topic 😛 Neutral VS Ground is still confusing for me… but here we go:
      We ran a badass 00 welding cable from the ground point between the driver/passenger seat, back to our negative bus bar of the house battery (there was no nearest “approved” ground point per BEMM). The negative of our inverter is connected to that bus bar.
      We connected the ground of the inverter to a ground point in the back of the van (per BEMM), but i’m not sure why… we did it anyway after reading a few articles here and there…
      The battery charger is not grounded, because the ground is provided by the shore cable (i recall reading this somewhere).

      Please feel free to correct or educate me! 🙂

      And thanks for the compliments! Happy Holidays!

    Hah! I’m in no position to educate anyone about this. I’m still trying to work out a diagram with all the parts and connections I need and have no hands on experience yet. What I’ve read about grounding the AC side of things has been confusing. It’s funny how easy it is to find good articles about marine wiring that sound like they’re written by electrical engineers explaining well established best practices, but I haven’t come across anything of that sort for RV wiring.

    Do you by any chance remember where you bought the cable clamps that are holding the cables and loom to the plywood?

      We bought them at our local electronics shop, but here is a kit with many sizes on Amazon: http://amzn.to/2nGxzY5.

    Thanks, the kit with many sizes sounds perfect!

    Hello, I am interested in how you connected your 12 volt lights together. Lots of splices or did you fabricate a “daisy chain”?

    • Comment by Antoine

      Antoine Reply July 5, 2017 at 2:24 pm

      I’m not sure what a daisy chain is…
      But our LED are wired in parallel using 3M ScotchLok Quick Splice with gel: https://www.etrailer.com/Accessories-and-Parts/3M/804C.html
      I don’t think it’s common practice (or recommended) to use this, but if we ever have to troubleshoot or replace one, we have easy access to them by removing a wood panel.

    Hey Antoine,

    Did you have to purchase more wire then you needed? ie a 100 foot roll of tinned 14/2 wire, instead of getting it by the foot somewhere?

    • Comment by Antoine

      Antoine Reply October 2, 2017 at 9:18 pm

      I don’t remember exactly, but I think we went through 100 foot of 14/2.
      We first bought by the foot, then bought an extra roll, i’m pretty sure of that!

      What make you hesitate?

    What an amazing job you guys are doing documenting your build, thank you so much! Although it’s too late for the “far out”, try using welding cable instead of battery cable. It’s considerably more flexible and easier to work with. Also, instead of crimping the lug… place the end with the opening straight up on a vice, drop a pre-sized solder pellet into it and heat with a small torch (available at any hardware store). When the solder is melted, remove the heat and just push the wire into the hole and hold till the solder solidifies. Since welding cable only comes in black, you can use red or black adhesive lined heat shrink tubing where the lug and wire connect to denote positive or negative leads. Aside from having a super great connection, this will allow you to do everything next to your vehicle and makes getting the lengths right easier. If I wasn’t clear, there are good U-tubes out there on soldering welding cable. I re-did a 6 battery system on a class “a” motor home using welding cable and life was so much easier.

    Hi Antoine: We love your webpage and of course your Van. My question: IS your refrigerator Nova Cool AC or AC/DC or 2 way? And if you were building your van again, What kind of refrigerator would you choose? 2 way or D/C. ? Yes, I’m confused with the choices. We are in build out planning phase here on our Ford Transit in Canmore, Alberta. Cheers Carol

      It’s 12V only, we would not use the 120V anyway… Our system is designed so when we’re plugged to shore power, all the appliances are still using 12V; the difference is that the power comes from the charger/converter in lieu of the battery. Hope that helps!
