I can open and close the tail gate of our 05 RX using the remote control or the dash button.

Thats an SUV with a hatch vs a trunk. I can close the hatch and both sliding doors in the Sedona from the cabin too.

Sounds silly, but they approach the engineering of a hatch and a trunk differently clearly.

Good to know. I thought certain models have that option.
When I tried to personalize our 17 ES I was told the trunk close option using the remote or dash button is not available on the ES.
My SA is not sure if it's available on the LS. I prefer to do it manually (push the button) for safety

SW17LS

No Lexus model I've ever seen has a power closing trunk you can close from inside the car.

I understand EU/rest of the world, have this option. The litigious US is another matter altogether...

any high end car audio shop should be able to follow my directions.. it's basically a 5 wire relay to the front switch using the trunk pin as the defining factor.. labor rates may vary depending on their familiarity with the car a few hrs..

How was the switch modified ?

I just did mine !
- Get one of this http://www.ebay.com/itm/QTY1-CAR-REL...72.m2749.l2649 ( any five pin relay that has pin 85,86,30, 78, 78a )
- Wire it up just like this
30-in from front switch
87a- tap to the BLUE wire next the BLACK wire in the middle !
87- you need to run a piece of wire from this 87 all the way to the back of the trunk opener motor harness, its the blue wire from right to left ( see picture below )
- Power source you can tap from anything that has constant 12v + with those 85 and 86 wire on the relay.
I will try to take it part and take some pictures for you guys to see.

Here are some pictures for those who really want to do this !

I have this feature on my 2005 Toyota Sienna minivan. Same company, same feature. I have both an interior button for liftgate (open/close) and same on my keyfob. I love this feature, especially when needed in carpool line. Was also looking for the same mod for my future LS. But additionally it would be nice to have either a foot operated control or an auto liftgate with waving of your hand on emblem like on the RX. Likely coming soon (approx Mar 2018) by Vaistech although probably costly.
