wiring 12 volt plugs to always be on

In my Tacoma I pulled out a relay in the engine bay fuse/relay box and rewired it so the accessory plugs in the truck would always be on, rather than being switched. I'd like to do the same in the 4runner. Does anyone know which relay(s) controls the 12 volts plugs?

Bump for this question.

I would also like to know if anyone has solved this issue of having not only all the 12 V outlets always on but the 120 V AC outlets as well as?

That link above did nothing but give me a headache.:redbrick:

I'll get it figured out eventually. :) But yeah, I'm also pouring through the service manual, and I haven't yet been able to find the relay (or relays) in question. I guess the last resort is to just start pulling relays until I find the one that shuts off the 12 volt plug(s), but I'd really rather not do that. :)
 
The Power Outlet (12V) (2010 4Runner) document shows how the outlets are wired to the fuse.

The Power Source (2010 4Runner) document on page 5 shows where that fuse gets power after the ACC Relay.

Looks like you could just move the supply of the P/OUTLET fuse to the violet wire to get it to be on with the ignition, or to the black wire to be on all the time.

I haven't done this, just looked at the schematics.

I was advised by my Toyota tech that you can't have the 120v A/C outlets "on" without the engine RUNNING. The power apparently can't be generated with just it switched on due to the load. I'm no electrician, but it makes sense to me that you'd need the engine running in order to create that much power. 110 is different than 12v dc. However, I'd be curious if anyone has other comments on this. :)

I'd bet can't isn't really the right word. More like really shouldn't or else your batter will last all of 30 seconds.

The 120VAC outlets are just coming off an inverter, which takes quite a bit of juice.

The 12VDC on the other hand are coming off the battery, so you could have them always on, although I imagine the argument is the same. You'll drain your battery eventually.

Really you just have to be careful either way. Toyota probably decided it wasn't worth all the dead batteries and ran the 12VDC outlets through the ignition.
 
Ryan is correct. It's coming from an inverter. However 400W isn't a huge load since that's the max load you can have, but if you ran that without your engine running you would drain your battery to below 11volts in about 30-40 minutes.

Thank you for being more specific in where to look, much appreciated.

I am also bringing my rig in to an auto/battery specialized electronics shop tomorrow to get them squared away with putting a second battery in the front right side of the engine compartment. I will bring in these schematics and let them monkey with getting the 12 volt power to stay on all the time.

I will post pictures of the soon to be dual battery setup when completed.
 
You absolutely can run an inverter on the battery. :) I've always had inverters in my cars, and I've always run them on the battery with no problem. The trick is how much power you pull from them. Running the inverter by itself with nothing plugged in will take a small bit of power, and beyond that it all depends on what you plug in. Running your laptop with 60 watts or so isn't too bad, and you'd probably get a couple of hours from your battery no problem. Running the full 100 or 400 watts would obviously drain it much faster.

I'm mostly only interested in just the 12v outlets myself. I'd like to be able to charge my phone with the car off like I used to do in my other cars. I sometimes forget my home charger when I'm on a trip, but I always keep the car charger in the car. I like to plug my phone in for a while to get it charged back up without having to run the truck. :) (And no, charging your phone will not drain your truck battery dead.) :)
 
I did the full time 115 AC mod as one of my first modifications. I am sure you can apply some of the info on my page in combination with the 5th gens FSM and get it to work. It does come in handy at times like for example when you are out and about using the digital camera alot, you can charge in in the rig during lunchtime for an hour or so and be good to go.

I'm not seeing these documents you're referring to. Is this in the HTML-based factory service manual that was linked up on here in another thread a while back? I'm looking at it now, and I don't even see page numbers. Just a navigation tree on the left with different categories.

There is a Power Source/Network category, but I've clicked through just about every part of that I don't see anything about the relays, etc. Only the actual 12 volt plug assemblies in the interior of the truck. Nothing about the real wiring behind it. :(

Excellent write-up. I would bet the relays themselves are the same (even if they are in a different location), so this write-up will probably give me what I need!

Did you ever do this mod? I would love to be able to have these plugs hot all the time.
