Incredibly frustrating.. no one here is promoting not wearing a seat belt. It's for the times when you're sitting in your car and not driving, or backing it down the drivewar for a second, etc... Let's be constructive and not throw unwarranted self righteous comments out there.
On to the real issue.. I tried the seat belt clicky thing it worked for 2 days then blam right back on. I tried the taking apart the buckle, and I too could not get the seat belt to click in until I forced it, which of course undid the slider.
I will do the under the seat disconnect and report back if I have any issue.. Now we've got to find a good system to disable that passenger side!
