We use a plug in charger / bluetooth adaptor in the lighter / power point socket. Its live when the truck is off, and flashing all night long.

I dont want to kill a battery, is there an easy way to make it switch off when turning off the vehicle? I tried the one for the rear seats too, also live 24/7.

In my mercedes W211 its as simple as moving a fuse over 1 notch.

 

I've been looing into this myself. Right now, it's coming down to installing a small relay that will will close the circuit to one of the under dash power port when the ignition is turned on (when the relay sees power). If I can find a circuit to tap into for that relay to power it up this will work great. I'm not sure if there is an easier way.

Maybe another member has done this before and give us both a few pointers.

 

Guys, just tap into a fuse or a line that only becomes active when the ignition is on.

So snip the power lead and find a switched source. Seems easy, wish there was a better way, but so be it

 

If you did not want to modify the SUV at all, you could probably build a small circuit that detects the alternator noise and turns on/off a transistor when it's detected.

Perhaps a less attractive but easier solution, a low voltage shutoff module is available:

It might be reliable if a point can be determined that the voltage does not drop below with everything turned on and the engine running that is still above the resting voltage of the battery with the key off.
A healthy battery might show over 12.8v on the bench but in-circuit it might never get above 12.6v.

I'd personally prefer to tap into something that maintains courtesy power for a bit, particularly if it's used for audio and you want it to keep working for a short time after key-off.

 

I was just thinking of just having them, or some of the, turn off when the door is opened, key off...

 

I dislike having the ashtray open to use the 12v socket and didn't want to run other accessories 24/7, even with dual batteries.
both left and right fuseboxes have tons of unused ignition switched fuses. I ran an ignition switched power from the right fusebox to a 12v triple socket, and taped it to the right side of the center console. Wires could be tucked easily under the glovebox so it looks clean.

you need standard size fuse tap, about 6 ft wire and 12v socket. No affiliation for items below

Occasionally I still use ashtray 12v socket since it is useful for charging phone and cameras while camping.

 

Im using the ones in the passanger footwell, so i dont have to have the ashtray ooen, but the rest of that is great info!

 

But isn't that one always hot? I ask because mine are.

 

They are, but i dont like the ashtray open all the time, its in the way.

 

Same here, I don't like the ashtray open. At first it sounded like you were looking for a switched sourced.

My current dashcam is wired into my fused box, but I bought a new one that came with a cigarette plug. The first dash came power source isn't powering the new one. Therefore I've to wire a female cigarette socket, and most likely I'll put it next to the two lives ones under the dash. This...

 

I *am* looking to have all power points turn off when the key is pulled out. Power live when key off ign on.

That is the goal. All my other vehicles the outlets are off with the vehicle.

 

Understood...

Same, now that you mentioned it so r mine, Mini, MBZ and Toyotas....nothing is simple about miss piggy I guess....lol

 

In my 9YO’s manual it says the electric outlets should turn off after 30 minutes but it doesn’t seem to but doing so

 

Wait, what year is your Cayenne?
For 955/957 the power to the sockets is always on.
