Passenger seat weight sensor?

[thezentree]

I put PRP seats in my 2001 SR5 last week and am curious if anyone knows how the airbag system works without the seatbelt and weight switch in the OEM seat being plugged in.

As in, if the airbag system sees both the seatbelt circuit and the weight sensor circuit as open, will it still fire the airbag? Do I need to jump the pins in the body-side connector to make it always fire the airbag?

To answer my own question (I found the FSM wiring diagram), the seatbelt circuits and the airbag system appear to be totally independent.

Did you check a wiring diagram for an 01-02 4Runner? When I swapped the bottom cushions on my 99's seats, I saw the same issue - an occupant switch in the passenger seat driver, but not in the driver. Searching posts that time gave me the impression that all it did on a 99-00 4Runner was help control the seatbelt warning light on the dash, but that it might control the passenger side airbag on an 01-02.

Yep it's a 2002 EWD. As far as I can tell, that's all it does on the later 3G4Rs too.
