I want to make a direct, under the hood, high current connection. The ground is easy. The positive connection is not for me at least. It was easy in my gen 3 and 4 Priuses. Just unbolted the output from the dc-dc converter on the fuse block and and my own lug with cable then bolt it back down.
Anybody out there done this with a 2019 or later RAV4 hybrid?
Please include pictures.
Somebody has to have done this for kilowatt amp or inverter or the like.
Thanks, John

Is there some way to use the jump start connection? If this is only needed on a temporary basis, the jump start connection will work, obviously fused around 100 amps. Coincidently, I am starting a 1000 watt inverter mod in my XSE. I am checking the fuse on top of battery to see if its the same 140 amps that is a Prius.

Here is the thread I started about my project. I suggest you watch the Prius video,


thanks Variman. My similar project is under the hood.

i would be careful about attaching to the lead acid battery in the rav4 or otherwise. The terminals will heat up with a 100amp+ load and will degrade the battery. I had the best luck with the gen3 prius connecting to the fuse block input from the DC-DC convertor just by adding a lug. Its not so easy on the 2019 RAV4

Thanks for the tip. I am good connecting under the hood. Do you think my idea is sufficient connecting the jumper blade in the fuse box under the hood?

So I ordered a AC/DC clamp meter to attach to my Fluke 87V Now I will be able to measure HV under the hood to find out if there is a stud off the inverter to pick up 12 volts. Why not so easy on the 2019 Rav H?

I would not mind the general location of perhaps a picture of this connection on the Prius as I also have this car. TIA if you can do it. The plan is a third back up form my wife nebulizer and possible O2 concentrator. I already have a tri fuel Yamaha inverter generator but one can never have enough back ups with critical medical devices.

Are you stating that the better connection is off the inverter 12 volt positive side?
Around 1:40 I see the red caps on the Gen 4 prius inverter.


I just bought a AC/DC clamp meter for my Fluke 87v so I will have to check.
