Terminal in under-hood passenger side fuse panel

[gmarcucio]

On the 2025 4Runner TRD PRO Hybrid does anyone know if this terminal in the passenger side under-hood fuse panel is connected directly to the battery? I want to connect a lead to it and run it out to the front of my grille area to connect a battery tender rather than opening the hood all of the time. My Pro sits without being driven sometimes and I'd rather keep a tender on it. This terminal has 12V to it at all times. Battery is located in the driver's side rear cargo area. I know to jump start the vehicle or connect a battery tender to it you connect to the terminal in the fuse panel under the red plastic cover identified with a +.

what does the HV manual show for under hood pics?

i thought i saw something along these lines about where you could connect jumpers to the engine bay.

Not sure what you mean by "HV" manual. But if you're refering to High Voltage I'm not posting about the High Voltage battey here. I'm posting about the vehicle 12 volt battery here. Like I mentioned in my post, to jump start the vehicle or connect a battery tender to it, you connect to the terminal in the fuse panel under the red plastic cover identified with a + sign stamped into it. You can see it in my picture. There is no way to secure a fastener to the jump start + post, or I would just use that connection post. But I want to be able to connect to a battery source in the fuse panel that I can install a battery tender wire permanently and run the wire out to the front of my vehicle to be able to plug the tender in without having to open the hood and remove the fuse panel cover all of the time.

“HV” is the owner manual for hybrid owners. If you have the Pro, that is your manual.

I am also curious about what that large terminal post is all about. Watching this thread…

Thanks for clearifying the "HV" for me. That was simple enough, just wasn't thinking, lol. Well I'm about to find out today hopefully. I don't have access to service manual information or a wiring diagram and I want to be sure before I use that terminal. I spent $72,000 for the Pro so I should be able to take a ride to my dealership and ask a technician. If he doesn't know he should be able to get into the service information and find out for me. I'm a retired high school Auto Tech teacher of 28 years and I would hope they would give me that bit of information as a professional courtesy.

I am sure you will, but please update us. As a TH owner, I'd like to make sure I know as well since the manual does not really state. I am glad I can use my jump pack on that positive terminal though just in case it is ever needed.
