Yes that one. Make sure to change out the cable from the trunk key cylinder to the luggage compartment door lock assembly. You need to use the cable for the lock assembly with the motor otherwise the pawl on it wont fully release and the power trunk will not operate. The guy mentioned it too.


For the hinge, its too much work honestly to change it. Looks like you have to remove the rear decklid to get to the hinge to see the marking, which means you have to remove the rear seats etc... If my bracket didn't work due to the angle to the closer motor, then I would have went with a new hinge. I was mainly worried that the angle may cause the motor to work harder so it may detect a high current situation and think that there's a jam of some sort and reverse direction (jam protection). But its been working ok so far *fingers crossed.

But I'd say install everything and plug it in. Then see if it works. Oh make sure that in vehicle customization that PBD (power backdoor) is set ON in the Techstream. Mine was already set ON from the factory, go figure lol.

Let me know if you need more help as you go along. Its worth thee headache to have the power trunk.
Thanks for all the help, I mostly understand what you did now.

Yeah I don't think replacing the hinge is worth the hassle, especially since you have to remove the hinge to see the mark to even order the correct one. I feel like if you get the wrong one the trunk lid might not close properly since the other hinge could be a different mark. I will measure and mount a bracket something like this:



Or bend my own with a kit like this:

Here is a picture of the mark on a Lexus LS trunk hinge. They just had to put it in the most inconvenient spot, like trying to hide it from you.

So I found out the reason there are 3 different part numbers for the hinge. It is an alignment angle. Stock would be 0, but if the vehicle has a body repair back there it could be different.

If your car has never been in an accident the correct part number for the driver side hinge for the power trunk is:
64520-30290

I was quoted $72 shipped to my door, by jp-carparts.com. I think it's worth the hassle to swap the hinge since I don't have to do it twice to check the mark. At least I'll have peace of mind that I would not inadvertently cause premature wear or have any issues in the future with a custom made hinge mount.

I would not cheap out and buy a used one, because an accident car could have a misaligned/bent hinge.

Yes, this retrofit is now a more involved mod, but I'm up for the challenge.

I think the torsion bar would need to be installed on the new hinge, might be a hassle.

You need to use a trunk spring tool. I changed the torsion bar on my previous car, easy to do if you have the correct tool. But for this car I don't think you need it, just release the tension by unhooking the spring from the side of the trunk. I adjusted the spring before because my lid didn't stay up initially(I think the spring was out of the socket).

Hey man, you took out the entire dash, this is a lot easier than that

I think I could make something like this work along with some washers, nut, and bolt:
Amazon Amazon



The hinge is a 1" square tube

LOL Boy I sure hope so. I need to install a bunch of stuff in the trunk anyways so I need to remove most of my trunk. That's when I'll really tackle this mod.

Pretty good idea but not entirely convinced though but can't really say why either. Will be interesting to see it in action none-the-less!
