R33 Gts25t Seat Belt Wires

[daxter]

Hey does anyone know what the wires coming from the seat belts are for? (Apart from turning off the seat belt light on the dash)

I noticed wires coming from the passenger’s seat belt and was wondering if there connected to the air bags in anyway.

they are for the seatbelt pre-tensioners. in a crash they fire and stop the seatbelt from moving. they lock it in place so you don't go flying fowards and just loosen the belt.

ahhh ok, thanks for that

Is that so?? Mine seem to have the mechanical teeth like most normal cars.. If you pull the belt hard and fast, it'll lock.

What I *have* noticed about the pre-tensioners, is that they tension when the ignition is on. The belt is really loose when the car is off, and has a fair amount of resistance when the car is on. When I turn the ignition off, most times I hear a loud mechanical thump from both sides of the car, and then the belt is loose.

you are correct. that is the pre-tensioners.
