4Runner Full Time 12V Power Outlet Modification

[@codypatron5968]

This is the only video I found for the 4th gen that shows which relay it is, very helpful thanks for sharing.

[@sksupply]

Cool idea. My Subaru and my Rodeo have front and rear 12v. I'll have to locate these relays. Even more power options in addition to the solar generators 😁

[@jeffl6089]

Jason, Awesome video. Well documented and easy to follow. Hey nice looking portable fridge in your cargo area!

[@kululv]

great video. But: never disconnect the plus! always disconnect the negative. If the plus or the tool touches metal you still can create a short!

[@Jasonoid]

Great tip, makes sense, thanks!

[@kpboix99]

Awesome, I didn’t know there was a way to modify that plug! I have a 4th gen also, cheers!

[@Jasonoid]

No problem 👍

[@rantzzzrantzzz2568]

Followed this without disconnecting the battery. Car died on me. Reluctant to try again!

[@kiver50]

Thanks for the video. I'm gonna be opening my 5th gen up to see if it's similar. Just ordered the Iceco TR 60L so I need this mod!

[@Jasonoid]

One thing I noticed is that my 4th Gen 12v outlet has way too much voltage drop over the cables because they used 16 or 18 gauge wires to the back of the 4runner. They may have made it better for the 5th gen but I had to run my own 8 gauge wires from the battery and install a second 12v socket and Anderson power connectors to avoid low voltage shutoff on my fridge. Crappy design on Toyotas part. My 12v fridges wouldn't start up without the engine running because the voltage was too low. Not the fridges fault but the crap junk wires they put into the outlet design.

[@kiver50]

@@Jasonoid ahhh got it. Makes sense. I'll have to think this through some more. Trying to avoid buying a portable solar generator and didn't want to wire directly from the battery. Might have to now. Thanks

[@Jasonoid]

@@kiver50 wiring directly from the battery to a back panel isn't bad at all. I did it on my 4th Gen and it took a couple hours max. Went easily through the firewall and the wires tuck under the door jamb plastic running boards. If you has multiple connections you could use a solar charge controller for charging and another port to run your fridge.

[@kiver50]

@@Jasonoid I’ll give it a look. I’m not the greatest diy guy so have to see how involved this will be. Especially with electrical. I do like the idea though. So an 8 gauge wire should work?

[@Jasonoid]

@@kiver50 8 gauge wire would allow for 40 amps charging or discharging. It would also remove most voltage drop over the distance from the battery to the back back of the 4runner. I think I needed about 22 feet in mine.

[@jr92648]

Can you make a video of the rear power center you built?? Saw it in fridge video, looks awesome!!!

[@Jasonoid]

Thanks JR, I have plans to make a video on it once the weather warms up later in spring :)

[@DirtCircusRacing]

Works perfect! Thank you!

[@Jasonoid]

Glad to hear it!

[@dosvaskosfarms4643]

That was a GREAT video! Thank you for sharing

[@stroudnick]

Great quality video, really descriptive videography! Project on the todo list. Cheers!

[@Jasonoid]

Much appreciated!

[@jeffreyacampora]

Well done!!! THANK YOU.

[@rantzzzrantzzz2568]

Great video. Thank you. Would this work on most car fuse boxes?

[@Jasonoid]

I don't think so since I bypassed a relay. I'm not sure other vehicles use a relay like this. If so, it's probably the same process.

[@Ace-hg2hy]

Great video, what battery are you running? And how long would you feel comfortable running your fridge with the car off? Also More 4runner content! Not enough 4th gen tips and tricks on YT

[@Jasonoid]

I think it's okay to run a fridge for 6 hours or so, maybe a little longer depending on ambient temps and how large your battery is. I use mostly my DIY 100ah lifepo4 battery, I also use some power stations on my shorter trips. I have tons of videos about that stuff on my channel. I have put in a power panel in the back of my 4runner with Anderson Powerpole and a secondary 12v plug, I'll do a video on that soon.

[@cachemoola2042]

Genius! Sheer genius.

[@ChrisJ-mf7cj]

Awesome info man! Crazy question, but would this work on my 3rd Gen Tacoma? Noticed a few 4Runner mods crossed over.

[@Jasonoid]

It should if you find the same fuse box. I know they are both very similar!

[@ChrisJ-mf7cj]

@@Jasonoid Well, that’s actually a no. I’ve got a 2017 Tacoma SR5 and it didn’t match up. I was really really hoping it would. But it seems like every year seems to have some wiring difference than the one before from what they tell me.

[@readyme]

Interesting. I have a 3rd Gen Tacoma off-road with the outlet in the bed. I wonder if I can do something similar to run a fridge off of a standard outlet.

[@Jasonoid]

Should be very similar to my 4runner

[@brandonholt1475]

Thanks for the tip!

[@Jasonoid]

You bet!

[@mikehicks3114]

That is a crazy place to put a relay, are these never expected to need changed out?

[@Jasonoid]

ive never seen one go bad before. With this mod we are just by passing the relay for full time power to the 12v socket.

[@eagleflownsouth7728]

@@Jasonoid can you do this to the front ones as well?

[@Jasonoid]

@@eagleflownsouth7728 I'm sure you can by finding which relay turns that outlet on 😁👍

[@CS-ui4qj]

i never even noticed that 12v adapter in the back of the vehicle..🤣🤣

[@hoffa1972]

do you have a fix for the 2021 4runner? We have a fridge in back as well. Hate that key has to be on!

[@Jasonoid]

In this video I showed my DIY power panel I built for running my fridges and charging my power stations / batteries while driving: kzbin.info/www/bejne/d4usc6B8d991fdU The stock wiring is too low in a 4th gen so I had to wire directly to the back anyways. It might be better in the 5th gen, but I'd still recommend running power from the starter battery to the back, it's pretty easy.

[@njsongwriter]

So this only affects the power on a single 12 volt socket and not all three?

[@Jasonoid]

Just the rear port

[@TOPOM42]

based on comments doesnt sound like same process for 5th gen. Whomp Whomp. How do you like the iceco? 45?

[@Jasonoid]

I love it, super efficient. Only uses about 10 to 20 watts average depending on the outside temps. I might be able to get a pretty good discount code soon for my viewers!

[@plaguedoctor880]

How does this work regarding not killing your battery by always running electronics even when engine is killed?

[@Jasonoid]

Just be smart and don't run your battery down. It's okay to run a device after the engine shuts off but it's your responsibility to watch the voltage if you make the mod. You can watch the voltage of your battery with a voltmeter and make sure it doesn't drop below 11.9v-12v. That's usually enough juice left to start the truck back up again.

[@seeno1]

Your led bulb is out on your temp display

[@24hrstolive27]

Can you keep the ac 120v on? Don’t want to drain the battery

[@Jasonoid]

My 4runner doesn't have the AC inverter. You wouldn't want to keep it running all the time due to the power draw it uses while idle. Only use the inverter while the engine is running.

[@BigglesworthNWATT]

Jason, I did the mod recently and only get an amp or so out of the sockets unless the car is running. Trying to find out if this is normal or not. TY

[@Jasonoid]

What do you mean you only get an amp without the car running? Can you go into more depth?

[@BigglesworthNWATT]

@@Jasonoid plugging in a power bank it will display however many Watts are being drawn. While the car is off it will show about 12Watts (1amp) until I turn the car on at which point it will jump to 90W. Used a voltmeter to check things and its supplying 12v when off and 14v when engine is running (alternator charge voltage).

[@Jasonoid]

@@BigglesworthNWATT the stock wiring is small and is causing voltage drop. I had to run a new set of wires to the back of my 4runner to run a 11v fridge successfully when the key was turned off.

[@signal4x77]

if u did this mod and then plugged in a power in inverter into the back 12v socket would it still run down the battery if u didn't have anything plugged into the inverter? (i.e. a fridge or cell phone charger)

[@Jasonoid]

The invert does use a little bit of powe (parasitic drain), so over time yes it would kill the battery.

[@signal4x77]

@@Jasonoid thank u. i figured it would do that. awsome video btw. i think ill just plug it in when i need it instead of tapping directly into the 12v.

[@lorrainefrost6285]

thx

[@Jasonoid]

No worries, it's a great mod!

[@ShortStackMedic]

Is there a way to have ONLY the front hot constantly? 5th gen.

[@Jasonoid]

I think the 5th gen is different than the 4th. Check the 4runner forums.

[@ShortStackMedic]

@@Jasonoid I have and I'm not seeing anything concrete. I ran my battery down last night with all of them powered and a WeBoost in the back. That's why I just wanna power the front and keep the rear on ignition.

[@Jasonoid]

Run your own dedicated 12v socket directly from the battery. I did that anyways since the stock wiring is garbage and you get a bunch of voltage drop.

[@ShortStackMedic]

@@Jasonoid probably what will end up happening

[@rantzzzrantzzz2568]

Is that the relay starter?

[@Jasonoid]

No, the relay is for the 12v accessories plug wiring

[@eagleflownsouth7728]

If you drive it everyday you can leave it plugged in

[@Jasonoid]

What type of device would you leave plugged in? It depends on how much power it pulls.
