Constant 12V power outlets

[Bumbo]

Cool trick! Now I can camp and charge my electronics without killing my battery:lol:

You can still run your battery into the ground with this mod... but it will just take a little longer when you don't have to key on.

If you hook up one up and rewire all your accessory loads to it... then you have leave it unattended and always come back with enough juice to start the car again.

Hey guys, a bit confused on this. I've got a 2007 Limited with just the 12V in the compartment to the left of the shifter ("ashtray" area) and one by the back hatch. Will this mod make my front 12V outlet be constant? Just want to clarify since they OP said it was for only his rear outlet.

Maybe I wasn't totally clear. I did this mod mainly to keep the rear outlet on but this mod makes both the front and rear 12V outlets constantly on.

Took a quick read on this thread. I haven't done the mod myself but I do have 10+ years of 12V experience and a bachelors and masters in EE. Something about the results from the thread doesn't seen right to me.

- First, my assumption is that the OP has bridge the high amp side of the relay. In a standard SPDT relay, this would be terminals 87 and 30. Generally speaking, either 87 or 30 is a fused 12+ constant. Bridging these terminals, you will effectively get 12V constant on the other pin.

- By this assumption, only the loads (accessories) that are on that circuit should light up. I don't understand why things like the compass comes on. Unless they on this circuit, but if this is true then why do some members have the compass on and others do not? (maybe different years or maybe some members just do not have the electronic compass.)

- If the compass is not on the same circuit, then perhaps some members are jumping the wrong terminals (i.e. 87 to 85 or 87 to 86.) But if that's the case then the outlets will not work.

Do you have any suggestions or alternative methods to achieve always on power to the rear dc outlet?

12VDC continuously ON circuit

10) Insert jumper from pins #3 to #5 (same location as copper blades on relay.) This bypasses the ignition/accessory circuit.

Could you post where you found the single blades with crimp sockets and wire ga. you used? Thanks for the great description and pictures!

Single blades are from any automotive supply store. Up here, I got them at Canadian Tire.

16 ga stranded wire.

This is helpful. I would really like to be able to have my phone charge while the car isn’t running. I’m going to try this one out.

Thanks you. Great thread, makes it look super easy to get this done.

Just did this, great mod! Hopefully no issues arise from it!

Great thread- Going to do this tomorrow!
Thanks KMVRETER

Has anyone done it like this on Gen 5?
Mine is a 2021 with a different fuse box.

 

[fitzmafia1]

Very cool. I will probably be doing this.

Could you add a switch to the jumper wire to turn the outlets on and off?

If you leave anything plugged in it will drain your battery. I did a similar mod by just jumping the 12v outlet fuse with add a fuse and jumped to an always on fuse spot and it drained my battery after a few days just having my tablet plugged in the whole time. I drove the car daily but Im guessing there's a power draw from all sockets when on even though you don't have anything plugged in.

I just did the "add a fuse" method someone posted previously for 5thngens. I connected 2 add a fuses together. Unplug the 15a "ACC" fuse. Plug in 1 add a fuse. Plug the other end of the connected add a fuse to the black spot (no fuses currently in space) on the other side, 4 down. It worked! Unfortunately my headunit and radio turned on too. Perfect for the drive in we were at. Not great for camping where I just want awning lights and phone chargers.

Thanks for the write up, doing this next weekend!

Thank you for this! I’m totally doing this on my new to me 99 limited

 

[tk421_99]

any clue if this is possible in the 5th gen?
