I'd avoid anything electrical from Harbor Fright...you get what you paid for. Cheap Chinesium is not, imo, what you want.

 

I looked all over the left third row seat and cannot locate the zipper.
can you post a pic please.

Does the seven to four pin adapter come with the LX570 or is it a separate purchase?
I just ordered this one from Amazon

 

Here are the items that came with my 2020…the dealer did not install the trailer plug or wiring.
Receiver Hitch, no ball
Trailer Brake Harness, I assume it is for the controller.
7pin trailer plug

 

Easiest if you drop the tailgate and lift up the rear window so you can get in there.

Look at the driver's side 3rd row seat. You'll see a seam centered on the rear of the seat.

At the top of the seat is a zipper control. Pull it down all the way, stick your hand in the opening, and see what you find.

Beyond simple.

 

thanks for the help…I found the third row center headrest.

 

Installed the trailer electrical plug this morning.
about a 10min job
used a 12mm socket.
NOTE: remove the dust caps on the truck connectors.

I sprayed all of the connectors with contact cleaner, then applied dielectric grease.
used Never Seize on the bolts and plug bracket to truck frame mount.

 

Looks like a good storage place for the 7-4pin adapter

 

Have you figured out what this one in the picture is for? I have the 7 pin plug installed on my car but don't know what this white one is..
My GX is 16 years older and also have what looks to be exact same thing in the glove box
