I'd solder a piece of wire to the pins. YMMV

Does anyone know the specs on these crimp pins on airbag connector

Hey all, just wanted to let you all know that my '09 was diagnosed with an OCS issue, which causes the airbag light to constantly flash. I purchased an occupancy sensor bypass from Airbag360 and after a two minute swap and airbag light reset I was good to go.

That just solves the weight sensor right? I wish someone made connectors for each seats airbag. I have tried multiple times and just frustrated. I would buy that sensor if there was another option for the connectors for each seat..

so is this the expensive but easy solution to the weight sensor diy? and do you still need a resistor for the airbag with this?

The unit is (probably*) just a resistor that is "tuned" to the resistance of the seat sensor when it is occupied. The resistor values I've seen used in the DIYs on this site are to emulate an empty seat. I haven't looked at the FSM in a while but, IIRC, the un/occupied values are in the FSM.

*Couldn't find a schematic of the unit but it's replacing a resistive element.

Is there any disadvantage to always having the seat sensor occupied? That would just mean that in the case of an accident, the passenger air bags would deploy even with no passenger, correct?

It's been a while since I look at the details in the FSM (link in my sig) but IIRC, you are correct.

If I were using the vehicle on the track, I'd go with the unoccupied option (assuming no passenger). On the street, occupied (just in case there was a passenger). YMMV.

I’ve also had good success with the airbag 360 module. Only problem is passenger belt light is constantly illuminated unless seatbelt is clicked

Couldn't you get around that with a resistor in the seat belt harness?

Djraunch · 03-27-2018, 10:14 AM

Maybe a more experienced member could answer but honestly I’m not sure. I just live with the light when I don’t have a passenger. The resistors in the airbag plug have functioned flawless for me with no light

I couldn’t get this to work. I ordered 4.7 Ohm, 1/2 watt, 5% resistor. Any advice?

That's a good question. I wish there is an aftermarket connector that we can just plug and play. Coz those resistors might not last long. It would be nice to switch out the resistors easily.

Worked perfectly for me last week during my install. Thanks for the DIY!

sirnixalot · 03-27-2018, 11:08 AM

do you still have the white plug from the seat belt plugged into the connector coming out the floor?

If so just disconnect it and the light should go away
