Do it Yourself- Disabling the Seatbelt Chime
You've all sat through that 30 seconds of loud chmes when you have something heavy on the passenger seat. Here are some instructions on how to disable the chime. This is intested for Off Road use, you should nver ride without a seatbelt with a passenger in the car.

modification of the seatbelt systems.
1.) Locate inside of seatbelt buckle (portion facing occupant). There is a small hole, and a tab. Push in the tab with a pick or small screwdriver. This will pop the sensor partially from the buckle.
The pick point is pointing out the tab to be pushed:
Grab onto the black plastic sensor and pull it down out of the buckle housing:
It's a long one, so pull it straight down and out of the buckle:
Flipping the sensor over, you'll see the infamous spring that needs to be ix-nayed. I'm using a pick to pull the spring up over the black stub:
Yes... the spring launched into orbit. If you want to keep it.. cover with your hand, etc. I didn't really care. I'll have this truck a long time.
The next picture is the same thing, minus the projectile-spring. The pick is merely pointing at the missing spring. The white plastic clasp will now stay down due to gravity regardless of if there's a seatbelt buckled or not. Keep your seat belt buckled to save lives!
***********************
VERY IMPORTANT UPDATE!!! ADDITION TO PROCEDURE FOLLOWING.
There was an issue with the passenger side airbag not functioning after this mod.
Now, to show you what needs to be done to correct this.
It's again VERY simple, but I think imperative to proper airbag operation.
I duplicated the no-airbag issue on my Tundra, and conducted various 'tests' to make sure this works.
Still with the sensor upside down, looking at the circuit board side of it, merely place a small piece of tape to inside the sensor, in the 'track' or path that the slider would slide up and down in.
Here's another pic:
The principle in the original attempt was for gravity to keep the sensor down. After inspecting my buckle, I believed the issue to be that improper engagement of the sensor back into the buckle to be the problem. Inserting and pulling out to re-insert can leave the slider in the sensor to hang up inside, and nullify the process we did here. To be honest, I'm no expert by ANY means, and this is the best I can come up with.
Please by all means, ensure the passenger side airbag is ON while there is a passenger (over 45lbs) and buckled up.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Now, reassembly is the reverse procedure.
See the first three pictures for reference. You'll be carefully sliding the clip/sensor assembly back into the buckle.
Be careful pushing it back up into the buckle. I had to make several attempts to get it just right-straight in there. It will require a little bit of a push, but it will 'snap' right in when done properly.
After the chimes are removed, and being that this whole job can take a beginner a few minutes tops, you wont need this anymore:
