Maximum electrical load for rear (cigarette) accessory port

I have the viar with the battery clips on mine. I am not sure which battery to clip it onto..
There is the starter battery in the rear left of the cargo, and then there was another battery attachment under the hood for the hybrid battery I believe.
Does it matter which one I hook it up to?

I think the battery attachment point under the hood is wired to the 12V battery in the cargo area wall. The under hood point is used for jump starting with ordinary battery cables running to another vehicle.
The hybrid battery is likely much higher voltage and not accessible to users like us.
I took a Quick Look at the under hood battery connection point and decided to try to find a more friendly air inflator power point so wife/adult kids could easily inflate tires in my absence without opening the hood. That’s what led me to the 85P. I’m going to take another look under the hood.

It looks like in the photos posted, there is a positive threaded stud that is common to the + that appears to be unused?

Probably not unused, but you could certainly tap off of it with an insulated ring terminal.
I have done no research yet, but I was expecting to be able to pick up a 120V inflator to plug into the rear 2400W inverter. Does that not exist in a portable size?
Do you have air at home? If not, there are plenty of the little tank style, 120v air compressors that might work as a home unit and small enough to drag along for occasional use. Depends on what you consider portable. One example: California Air Tools

110 Volt AC

I use a VIAIR 12v portable unit, stays in my recovery kit, is 100% duty cycle. I hook directly to the battery via alligator clamps. I also have a small Makita for home use and I wouldn't hesitate to drag it along if I thought I needed to air down and refill tires a bunch. Small Makita air compressor
I've given up on the 120V inflator idea. I didn't buy anything yet, but I intend to get something like the Viair or morrflate portable small sized units. The battery has pretty easy to access in the back.

No I didn’t. I decided to get the Viair EVC85P with a lower amp rating so it could be plugged into the 12V accessory (cigarette) port on the rear of the center console with less chance of blowing the fuse. The CFM air flow rating of that model is just slightly less than the 88P. I also have a separate 7-pin to 12V adapter so I could plug the Viair into the exterior 7-pin port if I want to.
I wish the Land Cruiser had a 12V accessory port in the rear cargo area next to the 120V port.

Has anyone confirmed if the 7-pin trailer connector is indeed 30 amps?

Can't tell for sure.......
Thanks for this. Someone else on this forum has been using a max 20a draw Viair via the 7-pin. Looks like the hot terminal is on a 30 amp fuse, this may actually work with the Viair 400P EF compressor. The compressor will only utilize the red [+B] & white [GND] terminals. Any thoughts on wire gauge to the connector?

Haven't checked, but I am running a "electric trailer jack" from my 7 pin with no issues.
It is super easy to install a pig tail to the 12v battery and you could use any gage wire and fuse that you wish. If you remove the battery trim cover and the red protective cover on the 12v battery, you will find an unused stud that's directly connected to the 12v battery, that stud is protected by a 250 amp fusible link. All you have to add is a nut.
I have 3 pig tails connected to that stud, one normal 12 pig tail, one "CTEK" trickle charger pig tail and a 12 cigar outlet. See my build page for additional details.
I may do what you suggest. Your build is SICK dude!
12 AWG for 20A Max
10 AWG for 30A Max
Confirming the 7-pin aux port on the trailer connector is indeed 30amp and can easily power a Viair 400P EF A compressor. This is an easy solution for compressor power.
