I have a 2023 premium GX460. I was searching for a 12V access point under the driver’s footwell in the fuse box and found an empty socket. It’s not connected to anything, and when I tested the voltage across its terminals, I discovered that it maintains a constant 12V. Could you please identify the purpose of this socket? I suspect it’s intended for a feature in the luxury model. Additionally, I’m curious about the type or model number of the male socket that I can use to connect my accessory to it. I’m also concerned about the safety of using this socket. The location of the socket is as follows: it’s zipped right in front of the fuse box in the driver’s footwell, positioned between the fuse box and the firewall.​​​​​​​

I can't help you on the exact purpose of this plug but I agree it is probably for a feature on the luxury model.

​​​​​​​As far as finding the mating connector, attached is the Toyota connector bible. In there is part numbers for housing and pins and how to repair and assemble connectors.

 

Thanks a lot! That’s a really helpful resource.

 

Interesting. My 2022 has it as well.

Odd they'd have an "exposed" 12v connector like that.

EDIT, I am going with provision for trailer brake controller.

They sell these plug and play kits and that harness sure looks close to perfect

Yep yep

 

Yes, it’s weird that a 12v connector is left open like that. I find the harness in the link helpful. I am just hopeful to find only the male socket, which would be of a fraction of the cost of this harness.

 

I found the harness on Amazon. I will order and try if it works and let you know. Thanks again!

I can confirm that this harness works and provide a constant 12v.
I also found the OEM harness that comes with the GX which is obviously compatible.

 

Good info thank you!
