Got these off ebay for less than $10. They are great. They allow the chime to still function so if passengers don't wear their seatbelt I don't get pulled over. But for hunting or mild trail riding I can plug them in and no chime or blinking light.
Work with the techs not the rep.
The techs careless and understand the annoyance of it. That's who took it off mine.
I tried having them turn it off. Typical deal, they said they couldn't, laws etc. blah blah blah.
even blinking light which I think is still on even if you get the chime disabled at the dealer.
Tried that too at the suggestion of a friend with an 06 FJ. I think I found out that the 5th gen 4Runners require the computer to disable it. I am happy with my solution, because I like the fact that I still have the chime for people who aren't wearing it when I am on the road.
dealer turned of my passenger chime for 40 bucks or so. Can be done
I'm pretty sure the seatbelt chime turns off automatically after about 15-20 seconds.
