Write Up: Working Airbags and Occupant Detection System with Aftermarket Seats

How To get the Airbag system working w/ aftermarket seats.
Step One: Flip bench over to reveal airbag wires. The wires are all in a loop, it’s just a matter of removing clips and zip-ties. You must disconnect the plug for the occupant detection system on the passenger side. Label EVERYTHING!

Step Two: Using a Phillips screwdriver, remove the passenger occupant detection computer.

Step Three: Remove the occupant detection thing. It’s a thin plastic air bladder that sits in between the cushion, a hard plastic layer, insulation and the metal support springs for the seats. Reach in between the plastic hard plastic layer and the air bladder and feel towards the front of the seat. There should be two plastic clips holding the air bladder. Reach for them and rip dat faka out. It is possible to take it out without ripping the small top portion off, but not nessecary as it has nothing to do with the actual occupant detection system; it’s just there to hold it in place.

Step Four: Re connect all harnesses to their appropriate locations, seatbelts, to the truck, occupant sensor and its computer. There are also two grounds that need to be grounded.

Step Five: Hide underneath carpet, or do whatever you want with the gaggle of wires you now have. Find a place to mount the occupant detection system. I chose to put it on top of the passenger seat as they will be covered in the future.
Step Six: Enjoy your working airbags and passenger occupant detection systems!

 

great write up

 

man that is awesome! great step by step write up!

now to find some seats

 

So, this probably applies to 05-08 regular cabs without bucket seats...

Thanks for the writeup Kelson.

I did not know there was a butt computer too. Gah! Thanks Toyota. No freaking wonder the buckets cost $2,000+ each. I was flirting with the idea of trying to transfer buckets into mine too. Now I'm less sure than I was before. I'm really tempted to just sell it and get the extended cab with the buckets already installed. The bench makes me fidget like a 2 year old on drugs.

 

lol i'm pretty sure if you can find 09+ buckets with the airbags, there probably is a way of swapping them. but prob pretty hard, as im sure there are more sensors in them then the 05-08 seats without the airbags, as they only have seatbelt and ass detectors lol

 

I did the same thing bro, I'm trying to locate an OEM passenger airbag on/off switch/plastic so I can bypass the stupid passenger seat bladder. The bladder is filled with an oil, when you sit on it, it puts back pressure on the switch which activates the passenger airbag. I'm going to splice those wires and use the OEM passenger airbag on/off switch instead!!

 

the earlier 2nd gen tacoma's came factory with the keyed passenger airbag on /off switch which was replaced with the bladder. I already installed the resistors to bypass the side curtain airbags and transplanted the computer occupant detection system wires/ seat buckles/ sensors. the only thing I need is that switch . I destroyed the bladder trying to remove it, oil all over the floor, LOL.

 

Sounds good man, keep me posted and vice versa! We'll get this sorted out seeing as we both have the same dilemma.

 

^ Pretty much says everything we already know, Can't expect Toyota to write a DIY on how to bypass airbag hardware, LOL

 

you never show re-installing the bladder in the new seats.where did you place them?

 

subed

 

Saving

 

So how can we override the seat airbags completely? I really want Corbeaus but I have OEM in-seat airbags...and I didn't see anything here to transplant the airbag, just the occupant sensor

What about the seat belts

 

Hmmm… @05Taco4x4
That switch you posted a link to has sold out a looong time ago. Tacomaholic has one but the spineless prick REFUSES to let anyone reverse engineer it / copy it! He’s a Real F*cking Dick Head‼️
