Full electrical camper conversion core wiring kit 12V

When you first choose to build your campervan it can be overwhelming trying to sort through all of the different ways of doing each individual part. Often people will reach the electrical system and decide that trying to work out what you need, what thickness wires, how many fuse boxes what type of split charger etc. isn't for them. That's why we came up with out full electrical camper conversion kits. We've taken care of all of the boring bits, allowing you to get on with the exciting part of installing the wiring and finishing your van.

Just tell us what you'd like wired in and where and we will make your wiring kit to suit.
Complete with labels around the end of the wires for an easy install.

Next to some of the description below, you will see links to articles on how to help choose which item you will need. Also at the bottom are some additional resources.

A complete, expandable tailor made electrical conversion kit for your camper van. This system covers the 12V side of things. In the "Add-ons" selection above, there is an optional plug in for the mains, off grid inverters and solar. Check out the how-to guide to decide what you might need.

Please note: If you have a smart alternator, you will need to use the CTEK battery to battery charger for your split charging.

Product description

Each kit is custom made to suit your individual conversion how we normally do this is by one of our layout forms (available in the attachments tab above). We have a blank one which you can fill out with your needs or we have some sample ones for more popular layouts. Either download the blank one fill it out and attach it to your order, or indicate the code for your sample layout. If you're unsure on what you need or where you'd like it to go. One of our team can give you a call, offer advise and run through the layout on the phone. 

Please be sure to leave an email address and a contact number when ordering in case we need to discuss your layout with you. 

Cable routing. As we design the wiring looms, these looms will have ample cable to reach each components, allowing for sensible routing, we do take the shortest practical route, which we usually define as around the perimeter of the van at floor level and then up to components, with the exception of light looms which run up into the roof from the switch and then around the roof. If you have a specific cable routing in mind, please let us know and we will do our best to accommodate this. 

We won't plan to run cables under the floor, as we know this is often the first part you will do in the camper and don't want to be held up waiting for wiring to go under the floor. 

With this kit, we aim to supply all of the wiring, fusing, switching and charging you need to put a 12V system into your campervan. All you will need to add is the end components, e.g. fridge, water pump etc. The only specialist tools we recommend you get are cable fixings, (cable ties, adhesive cable tie bases, "P" clips etc.) and a set of basic crimp terminals to make the joins between the wires coming off your fridge, tv, water pump and the wires we give you. 

When driving your leisure battery will be charged from you engine automatically through the split charge system.
