Hello, I am trying to stop the seat belt alarm from the front passenger. I found the wire that goes from the seat belt socket in the Yaris Service Manual (and double checked it), but when I unplug it to see if I can just add a switch to short it, it turns off the airbag but not the seat belt alarm.

Here is what I have gathered from probing

-The socket part of the circuit has a resistance of 3.33 megahomes
-when I insert the buckle, the resistance does not change
-The resistance does not change when I sit on the seat (meaning I did not accidentally probe the scale mechanism, although it has a giant connector with many wires so it would be hard to mix it up.)
-When I close the circuit when the socket is unplugged from the circuit, the airbag does not turn on but nothing happens for the alarm

Any ideas?

thanks!

Julien

not gonna lie, not exactly sure what in the world ur talking about, lol. but i my experience (if 3.33megaomes is the correct resistance) if ther are 4 wires going into the buckle, 2 wires need to be connected to a 3.33 resistor and the other 2 wired to a switch or together.

i think i have restated whaqt u planned on doing....lol, iunno, if not, give it a shot! lol

lol sorry about the lack of clarity. I am trying to make it so that the annoying sound does nto go off when I have weight on my front passenger seat, but no seatbelt plugged in. I can't for the life of me figure out where I could add a switch to make a false "seatbeld fastened" signal so the car can shut up :p

I know it stops after 30 seconds and I can just get a scrap buckle or whatever, but this solution would be cleaner\cooler.

thanks
