Power down outlets when engine is off?

[Supreme Pizza]

Whats the easiest way to have the 12V power outlets shut off when you take the keys out?

 

2008 'Burban.

 

Pull the fuse for the cigarette lighters, and run a jumper to the one side of the terminal from another circuit that does not have retained power?

 

A full on relay configuration for the whole circuit?

Maybe run a jumper. I would test that out first

I was thinking about a jumper from another circuit. I have dash cams and other electronics that I want powered off at night. I guess I could hard-wire them to another power source.  Too bad there is not a simple switch that I could click to control the power when the rig is off.

Carry an 8mm wrench with you at all times and unbolt the battery

One of my complaints with GM. Even my on my Avalanche the power outlets stay hot. Your not going to leave stuff going with it off in most cases.

I believe the next generation in 2015 started offering the ability to simply move a fuse that would change the functionality of the power outlets to be hot all of the time or only when the vehicle was running.  I'm not sure if your generation has this function but you might want to reference the manual.

I feel like this has been an option even on the older vehicles too. 3-prong fuse holder in fuse block on driver's side. Having fuse in 1+2 would be like accessory power and 2+3 would be constant hot.

Yes.  I haven't peeked at mine but I believe that's how it works.  Mine is set by default to cut power when the ignition circuit cuts power so that's how I really like it and find no need to search further.

I appreciate the tips fells. I will have to look into that. Now all I gotta do is figure out which fuse.

Check your fuse panel to see if this helps.

Thanks for all the info guys, I will check it out and report back any findings.

No luck. My fuse box doesn't look the same as the video. It doesn't have any of those larger fuses, just all standard flat fuses. Any ideas?

Looks like you might have to rewire and interrupt your accessory outlets using a relay.  Use the ignition circuit to "trigger" the relay to allow power to flow through the factory "always on" circuit.  Seems fairly straight if and only if one possesses knowledge of relays and wiring in general.

I think you right. Probably have to rewire. It would be nice to just move a fuse instead, but I guess that wont work. I remember having to do the same thing on my '03 Burban, but I was hoping that there was a simpler solution on the '08. I seem to spend a lot of time wiring my rigs. Fog lights, DVD stereo system installations, backup cameras, hidden kill switches (anti-theft), etc.

Did you ever figure out how to do it I have the exact same fuse box. Would appreciate you sharing
