I need to find a live feed - preferably in the Dash Fuse Box, that is only live when the ignition switch is in the run position. Anybody got any information, please? 2017 290.

not long enough
I found out when mine failed that most if not all chassis have a D+ terminal point

Not that it will help you but on my Mercedes I now know it is under the drivers seat

mine has three terminals, permanent live, live on ignition and live only when engine running

hope that helps even if only a little bit (y)

More than toes wet now!
Ours is an X250 (13 plate) Ducato so maybe not the same layout as your X290.
I piggybacked our dashcam hardwire kit off F49 which is ignition switched.
Note it's only a 5A fuse in our board but as the dashcam is a low draw comfortable the wiring will be sufficient.

Sorry, thought you were cracking a joke. Radios have been wired independent of the ignition circuit for the last 15 years or so. That's so you can listen to the radio with the engine not running, like on a site.

After finding no fuses that were ignition controlled I finally solved the problem by running a cable from the cigarette socket. This switched on a relay to connect the Inverter to the vehicle battery only when driving. The idea is to use this to charge the Laptop.

News to me. My 2005 Hymer & 2012 Le Voyageur were both wired to OEM connections.

Nope ... our dealer fitted Kenwood can't be used with out the flipping ignition on (no engine running needed)!

You must have at least one permanent live somewhere as the radio would loose all stored info

On what vehicles?

We deal with several new motorhomes everyday and the most asked for “ little job” is rewire the radio

White wire/ black trace by the way from ignition switch to fuse board is the +15

AFAIK factory fit Fiat Ducato radios are wired as standard to the ignition circuit, as with cars. That was the case in my 2008 Adria as well as all of the cars I have had that I can remember. They all have an always live feed to maintain the memory, but it is not used to work the radio. My 2015 Hymer radio/CD/Sat Nav/reversing camera/ was wired to the hab circuit, but that was only because the dealer got it fitted and specifically requested it that way.

Our 2015 Fiat Ducato with factory fitted U-connect OE radio works with ignition off. This also applies to Volvo S80 and Toyota Yaris all 2015.
From memory our previous vehicles 2010 and 2009 Ford's were same. All worked fully with ignition off key removed.

It is possible you take a feed from the leisure battery through a diode to the radio power socket. You then fit a diode to the feed from the ignition to the radio. When the engine is on you get a feed from the engine and leisure battery. When the engine is off you get the feed to the radio from the leisure battery. The two large diodes stop current flowing between the two batteries. That’s the way Pilote do it.

We've been putting the rear-view camera cabling in today and will fit the monitor and finish it off tomorrow so are going to have a play with the radio as well. As we were doing the cabling I suggested that we should simply do a direct feed from the leisure battery (with an inline switch) rather than mess about switching it to the ignition when driving - as we have solar panels fitted it doesn't really make any difference where the power is actually coming from, however he seems to believe that taking off the removable radio front cuts the power anyway (just leaving it for the memory etc), so if that's the case it's another thing we can consider too.

I too am fitting a rear view camera. I would like to take the power from the main electrical distribution board which is in the garage of my Ducato-based Rapido 763F; it is closer to the ignition-controlled outlet and fuseboard. Does anybody know which contact in the distribution board is only active with the ignition on?

That should read " closer THAN the ignition-controlled lighter outlets and fuseboard". Sorry.

Chances are, on a foreign van, the ignition will have no control over the hab electrics whereas many UK vans the ignition turns off the hab electrics except fridge and split charge.
You're going to need to run audio and video cables from back to front so power it from the cab fuse box.

Thank you for that. But the camera I am fitting has Bluetooth connectivity to my SatNav, so I don't need those wires. I just need power which is ignition controlled.

Fridge supply will be your best option then. Only live with engine running unless Johnny foreigner does different and wired it to the hab battery.

Thank you. That sounds like a good idea. I should have thought about it myself because I have had a frig problem and know which fuse it is.
