Our 2008 Tribeca has two 12V accessory outlets in the center console. Great feature! The bad news (to us) is that the outlets are fed from switched power. So are the ones in the back.

Found the fuse for the center console and determined that it always has power. The only conclusion I can come to is that the wire feeding the outlets goes through a relay that is energized when the ignition switch is "on" or "acc".

I've pulled all of the likely looking plugs, one at a time, from behind the block in the engine compartment that contains the relays and fuses. None of them seem to contain the wire that feeds the accessory outlets.

Is there a tidy way to bypass the relay and have power always on to the accessory outlets including the original fuse? Front or rear - I don't care. I can do a shade-tree mod and run a wire with an accessory outlet attached to 12V under the dash or through the firewall but would rather do it in a way that retains a factory appearance.

Thanks,

Dave

Well if you found the fuse, all you have to do is run a wire directly from the fuse to outlet. You can get fuses for accessory wiring with a tail to attach your wiring to at Pep Boys or a local car parts store.

Just curious want you want constant power for? And to point out the obvious...most car outlets are switched now so you don't drain you battery;)

Unswitched To Keep GPS Alive

We have a GPS (Lowrance 500c iWay) that operates on external power only. When the ignition is turned off for any reason (e.g. fuel stop) the GPS goes off and must be manually turned back on when the vehicle is restarted. The GPS then takes several moments to spool up and re-orient.

The GPS is moved between the Tribeca and the GMC Envoy depending on which one we take on a trip.

In 50 years of driving I've never run down a battery by leaving something plugged into the cigarette lighter/accessory outlet. If I do, then I deserve the consequences. Frankly, manufacturers' actions to render ineffective the actions of stupid people is getting more tiresome by the day.

Yes, I know about fused pigtails of which I have several. Running an external wire to the fuse block is kind of a Dogpatch way to do this. I was trying to find a way to use the existing wiring.

All that said, input was requested and I do appreciate the time taken to reply.

Thanks,

Dave

Other cars

I rented a Buick Lesabre more than 5 years ago. It had a switched power outlet. Upon reading the owner manual (gasp) I discovered that the fuse had 2 positions to be inserted. Center-left was switched, center-right was un-switched. Now that's a good idea!! Personally I like unswitched. Only time I killed a battery is with an old Escort radar detector in my 1979 Camaro that I didn't drive for a few weeks...

This is very similar to a dummy relay available from Mopar for the same purpose. Jut get an extra relay and install a jumper inside.

I found the relay that controls power to the center console outlets and bypassed it. The modification, with pictures, is on the scoobymods.com board. Here's the link.

Dave, thanks for the link. I did this today, now I want to do the same thing to the two rear outlets.
I jumping out all of the other 7 relays, but none of them go to the rear outlets.
Does anyone know how they are controlled or have a link to the schematic?
Thanks in advance.

Accesory Relay 1, but it also powers up the seat heater relay, accesory relay 2 and mirror switch. So ther is a potential to leave other stuff on as well.

BTW I have access to wiring diagrams if needed.

Swooten, thanks for the info.
I'd appreciate the schematic if you can post it. Or just send me a PM and I'll send you back my email address.
The rear outlets get powered thru fuse 13, not sure where F13 gets it power from.
I was thinking about running a new fused power feed to the rear outlets.
