DIY: [How-To:] Racing Seat airbag light fix

12nismo · 07-18-2012, 03:51 PM

Does anyone know if you can buy the finnished set-up (plug and play) instead of the DIY (stripping, soldering, etc.)?

12nismo · 07-18-2012, 04:00 PM

I guess what I'm wondering is if anyone sells this? \/

martin82 · 07-18-2012, 04:08 PM

you can just solder longer leads and plug it straight to the plug or even slide the resister into the harness and just tape it up...

has anyone measured resistance on the passenger weight sensor? I will be installing both racing seats so I will need to figure something out here. I prob would just like to wire it so the air bag thinks there's always a passenger and not transfer the weight sensor (needs removal of seat) per the service manual.

I will be in the same boat in 2 weeks or so, I will see if I can find impendance when someone is on the seat and without it.... see if 1) can make a toggle switch without the sensor or 2) leave it on all the time...

I know the DIY says 1/4 watt does it matter if I use a 5 watt?
I know the difference is how many watts it can take before burning up so technically it should matter right?

Technically I think that's right ... I think the 4.7 Ohms fools the system, and like you say the watts only comes into play if the system says to deploy an airbag ...

martin82 · 07-19-2012, 12:33 AM

I will have to see but I don't even think it makes a difference if the airbag blows, other bags will still deploy no issues as long as the 4.7 ohms is there...... But I have no idea how it works. From what I remember in highschool the more watts is just that how many watts until it burns up...... Maybe someone else has more insight on this?

Picked up a 2 watt 4.7 ohm resistor frys didn't have a 1/4 watt. Also picked up crimp connectors I can stick straight into the harness or also bought a made cable I can solder the resistor too and modify the plug. Maybe this weekend I will measure ohms on the passenger seat weight sensor and see what I gotta do.... I will update again once I do

That would be cool ... I would love to fix mine so it thinks someone is sitting in the passenger seat ...

martin82 · 08-10-2012, 01:24 PM

I have spoke with a few people, didn't get a chance to do this myself, it looks like it is not just a matter of the right resistor for passenger side, we think it is actually sending information to one of the air bag modules............ I will give it a go in the next few weeks, for now my air bag light just blinks.......

I hope you guys figure it out because I would like to put racing seats in my car but I don't want any flashing lights going on, and I really want to keep the passenger side airbag armed.

Until then, i will hold off. Great info in this thread.

Is there any update on this? I want to change out both seats without taking the weight sensor out.. But if the passenger airbag doesn't work I can't risk putting my girlfriend in the car just in case of an accident.

From what I understand, removing the weight sensor out of the OEM seat and installing it in the new seat is pretty simple and straight forward. I have a few friends who have done it.
To me the bigger concern is getting the lights off. Either way, my seats are on the way. As soon as I get them in, I will report. Should be within two weeks.

Anyone know if it's possible to buy all the harnesses separately and the weight sensor ?? Can't find my stock seats -___- been lagging on doing this bypass now that I moved back in Idk where my stuff are in the basement total mess down there still
