400W Anytime Wiring Harness

MPN:CR2405

This plug-and-play harness is designed to keep the factory inverter at 400W while the truck is in motion without any splicing! That means the inverter won't kick down to 100W and turn off your fridge as soon as you start driving. Simply plug the harness into the factory inverter located under the center console and attach the ground terminal to a nearby bolt. Included in each kit is an optional extension so that you can add another 3-prong outlet in the cab where it is more useful (Outlet not included). Order Toyota p/n 85530-35050-C0 from your local dealer or purchase the complete Outlet Upgrade Kit here. Now you can utilize the factory inverter from the comfort of your cab!

Will work on these models:

2005-2023 Tacoma

2010-2024 4Runner

2007-2014 FJ Cruiser

2022+ Tundra (NON-HYBRID)

It works for 4runner!

This is a good wire harness for 4Runner too! The difference to the instruction video is that 4runner's 120V outlet is in trunk, you will need a tool to open that 120V outlets panel from its bottom and then you'll find the connection. Disconnect the OEM connection then insert this wire harness, there is a bolt inside for your to ground it.

Works as described. Allows me to run the outlet at full power while driving.

Thanks for the review! Glad to hear the 400W Anytime Wiring Harness is working exactly as expected and gives you the outlet power you were looking for while driving. We appreciate you sharing the feedback.

Works Great and simple to install

Install would have taken less than 5 minutes except My tools haven't seen the light of day since retiring (5 years), and had a difficult time locating a 10mm socket. Should have a dozen of them. Didn't have the approved plastic panel tool, but careful usage of a thin putty knife sufficed for the job. Opened from the bottom inside corner side (putty knife was too long to fit from the bottom. Pried out then was able to grab to extract the plastic panel without any damage. The connector itself was a bit tight, but using a small flat blade allowed me to push the lock down to wiggle it past the lock and remove it. I then removed the 10mm bolt, added the grounding wire, and reinstalled using the new harness and retightened the bolt. Only plan on using the one outlet with a chest type refridge from Aldi, so no need for the second cable. Keeping it handy just in case I find a need at a later date. 5 stars for ease of installation and 5 stars since no splicing was required.

Thanks for the detailed review! Glad to hear the 400W Anytime Wiring Harness was quick to install and that the no-splice setup made the job straightforward. We appreciate you sharing your experience and the 5-star feedback.

3rd gen Tundra

Works great on my 2023 Tundra platinum. Easiest install ever, literally no tools and took 5 mins. I got it to run an electric cooler in the bed when traveling and for long distance costco runs.

Amazing - wish i knew about this earlier

5 minutes later and i got all time 400w

First harness sent did not work. Contacted customer service and they immediately sent another one which works as expected!

Easy installation on ‘23 Toyota Tundra Limited. Just popped off two rear pieces of center console (cup holder and vent/rear outlets), unplugged from inverter, plugged in this harness and closed back up! Now can run my travel fridge/freezer on long trips!

FedEx lost my alternator charger

FedEx lost my alternator charger that was supposed to keep my EcoFlow Delta 2 topped off. It’s been a month with no resolution, after doing some research, the 400W anytime wiring harness popped onto my radar and has been a huge improvement and stopgap until my alternator charger finally shows up. The wiring harness took 2 minutes to install and works as advertised. I highly recommend.

Plug and play!

Works like it should. Be very careful prying the plastic as it's very easy to break. Once installed, 400 watts of power will be available while driving. Make sure to check electrical system voltage while driving to know what the alternator voltage should be producing before any load. Monitor for warm wiring after extended use. I use a voltage meter USB plugged into cigarette lighter unit to monitor voltage drops. Alternator should be producing 13 + volts while charging the battery. Anything less should be investigated.
