You are very welcome. It is in an awful location. I hardwired my dashcam into that fuse box, and may never recover from the experience.

Ditto.....almost impossible location to work on. I also did a dash cam install and the fusebox was the most difficult part of the whole process!

Look in the fuse box under the dash....very tight fit.

I used the tap shown in Post 138 in this thread to power my dash cam. I don't recall the number, but you can use the picture in that post to find a good fuse location to tap into. The power for the LED should be low enough that any available slot would work ok I assume.

See this thread post 138

Since I'm going to install LED strip light under the hood, can I tap to a fuse inside "Engine Compartment" fuse box (which fuse would be recommended) or I have no other choice but to run wire thru "Driver's side instrument panel" fuse box? Thank you

I have a similar question. I added front parking sensors in the 2 locations that would have had them had the original owner ponied up like $300 or Lexus included it in all cars(like they should) anyways I want to tap the stop/brake light so the sensors aren’t activated all the time. The easiest would be to tap in the engine bay but I only see STOP fuse in the cabin fuse box(7.5a). I read that tapping the stop light would be a best for my application seeing when parking you will be applying your brake. I also agree about the location of that dam fuse box. I’m 5’11 185 and I can’t fit down there. Not to mention trying to locate a spot to pass the wire through from firewall. Any info appreciated.

Default "Seeking Help: Rear Defrost Location Mystery in RX350 4th Gen"

[QUOTE=dhargyal97;11651465][QUOTE=dchar;10176025]


Here you go...took off the cover when I installed a fuse tap for a dash cam.

Does anyone know where the rear defrost is located in the 4th generation RX350? I searched under the hood panel without success, and even checking the fuse location under the steering column didn't provide information about the rear defrost fuse. Additionally, the owner's manual doesn't mention anything about it.

There is another post on this from a few days ago.

Lexus removed the fuse "key" from the manual a couple of years ago, so know what is where is very difficult.

The only thing that I can think of is get the diagram key from the dealer, or go onto TIS (official service site) and see if it is there.....minimum 2 day subscription fee.

If anyone has it/finds it....please post.
