VW Transporter Camper Switch Panel Layout Guide (T5/T6)

The Problem

When converting a VW Transporter into a camper, you need a clear, prescriptive starting point for what to include on a switch panel and how to arrange the controls. This guide gives you a tested layout you can adapt, covering controls, 240V and 12V sockets, USB charging, heating controllers, and environmental sensors. Because the T5, T5.1, T6, and T6.1 have meaningfully different interior profiles and B-pillar/D-pillar trim depths, check the available depth and mounting points behind any panel against your specific generation before committing to cuts (confirm this applies to your T5/T5.1/T6/T6.1 generation).

Solution

1. Cut a removable plywood panel and secure it with a couple of screws so it can be lifted out for access to wiring behind it.

   • Mount all main controls here: thermometer, inverter switch, 240V socket, Victron Cerbo GX display, USB sockets, 12V socket, and light switches.
   • Before sizing the panel, check the trim depth at your chosen location — T5/T5.1 and T6/T6.1 differ here, and shallower pillar areas may not clear deeper components like the Cerbo GX or recessed sockets (confirm this applies to your generation).

2. Mount the diesel heater controller (Eberspächer or Webasto) separately above the rear-view mirror rather than on the main panel.

   • This keeps the main panel uncluttered and puts the heater control in a natural, easy-to-reach position.

3. Offload switching functions to a Victron Cerbo GX unit where possible, using its touchscreen or app to control the inverter, RGB lighting, and fridge power instead of physical switches.

   • This can dramatically reduce the number of switches needed on the physical panel.

4. If you prefer a minimalist look, hide switches in discreet locations: a 3-way rocker on the B pillar, under-cabinet switches for downlighters, and pocket-mounted switches for rear lights.

   • B-pillar trim depth varies between Transporter generations, so verify there is enough clearance behind the trim for a rocker switch and its wiring on your van (confirm this applies to your generation).
   • Battery-powered, motion-activated USB lights can eliminate wired lighting switches entirely.

5. Keep the inverter socket clearly separate from hook-up sockets by fitting it under a protective flap or labelling it prominently to prevent confusion.

   • Wire a mini consumer unit with twin RCBOs from the inverter and tuck it into a rear cupboard side panel.
   • Specify your wiring to suit the load: for typical UK 230V camper socket circuits use 2.5mm² (e.g. 6242Y twin-and-earth or 3-core flex) protected by a 16A RCBO, and 1.5mm² protected by a 6A RCBO for any lighting circuit. Size the inverter feed cable to the inverter's continuous output — for example a 2000W inverter draws roughly 8.7A at 230V on the AC side, but well over 160A on the 12V DC side, so the DC cabling and fusing must be rated accordingly. Set your total AC amperage budget below both the inverter's continuous rating and the incoming RCBO rating. (Verify all cable gauges, fuse/RCBO ratings, and the amperage budget with a qualified electrician — 230V mains work in a vehicle is safety-critical and may need certification.)

6. Use domestic-grade black switched double sockets (switched on both line and neutral) rather than proprietary campervan sockets if you prefer the aesthetic.

7. Flush-mount the Victron Cerbo GX touchscreen display into the panel, working to precise measurements and securing it from behind where depth is limited.

   • Measure the unit's footprint and required cut-out, and check the rear clearance needed for cabling — (verify exact dimensions and required mounting depth for your specific Cerbo GX / GX Touch display before cutting). The display is light, but support it on at least two opposing edges so the screen is not held only by friction.
   • Rather than improvised Meccano strip, prefer purpose-made fixings: the manufacturer's mounting bezel/frame, small zinc-plated L-brackets or mending plates screwed to the rear of the plywood, or a VESA-style bracket if your display supports it. Improvised brackets are acceptable only as a temporary measure and should be replaced with a rated fixing.

8. Fit 60W power delivery USB-C and USB-A dual sockets on the panel, and retain any factory-fitted USB chargers in the D-pillars if already present.

   • A MagSafe-compatible magnetic phone mount placed next to the USB sockets adds a convenient wireless charging spot. Note that MagSafe magnetic alignment and wireless charging only work with iPhone 12 and later; older iPhones and most Android phones will not attach magnetically and need a different mount or a cabled charge.

9. Use RuuviTag (Bluetooth environmental sensors) for temperature monitoring in three zones: outside (fuel flap area), inside the cabin (wall panel at head height), and the equipment bay (near the fridge, MPPT, Cerbo GX, and inverter).

   • Specify the model when ordering — Ruuvi sells the standard RuuviTag and the RuuviTag Pro in several hardware revisions with different Bluetooth range and sensor accuracy; for an equipment bay buried behind panels, choose a current-revision RuuviTag Pro for the better range (verify the current hardware revision before buying).
   • Read data via the Ruuvi app rather than a dedicated panel-mounted thermometer display.

10. Spray-paint any cream-coloured consumer units with Plastikote paint in black to match a dark panel theme.
