Race seats and airbag light.

You making a mountain out of a mole hill. All you need to do is transfer all your wiring and passenger seat bladder to the new seats, I'd done it and so have many others. It's not rocket science. I have Corbeau seats for over two years without any problems, and my wife rides in the passenger seat. Don't pay attention to all the engineers without a Diploma that are scaring you.

Mind doing a Write up or linking your source's?

I will do when I'm done if I decide to go this route. It won't be for another few weeks. I'm sure it will come in handy because there isn't an actual good write up. And all my info is from like 8 different websites and forums. I wouldn't wish posting that nightmare on here for you guys.

Thanks for the heads up geo. Would you mind confirming that it is infact a 1.7-2.5 ohm resistor that you used.

I did a How to, I can't find it now, but I know is out there. each photo has a little how to/why and step by step. I will keep looking, I maybe searching in the wrong places.

I saved this from another website. This guy researced this extensivley. You need to add the terminator for sure. Read on.....
Aftermarket Seats in the S197 Mustang with No Alarms

The Seatbelts
I started out with the procedure in the owner's manual to disable the seatbelt warnings - flashes and beeps! The only other trick needed to satisfy the seatbelts is to plug the sensor in under your new seats.
This will take care of the seat belt chimes:

1) car off, all belts unbuckled, parking brake on
2) turn key to on position. you will see seat belt warning light light up red
3) after 1 min, light will go off, now you must buckle and then unbuckle seatbelt you want to disable warning for 9 times exactly and finish doing this within 50 seconds of the light going off
4) airbag light will go on for 3 seconds or so
5) after it goes off, buckle then unbuckle seatbelt again 1 time
6) light will flash, seatbelt warning disabled.

The Airbags
First a word about the error indications.
DTCs are Diagnostic Trouble Codes. You will need an OBD-II scanner to read these. The problem is the codes related to the seats are body codes which are part of the enhanced set of OBD-II codes. You will not be able to read these with a handheld programmer like an XCal-2 or Diablo, you will need a special scanner capable of reading these enhanced codes.
LFCs are Lamp Fault Codes. They can be read right after key on ignition off by watching the airbag light in the cluster. The LFCs are 2 digit codes and are read by the light flashing a code. For the example of LFC 49, the light will flash 4 times then a brief pause then flash 9 times then a long pause. This will repeat 3 to 4 times then the light will stay on solid.
DRIVER’s Side
To satisfy the computer and not have any lights bells and whistles after installing your aftermarket seats you will need to take the harness from the bottom of the stock seats and put them under your aftermarket seats. Here’s a pic I borrowed from someone else of the harness under the driver’s seat. Notice things like the seatbelt receiver had to come with it, the yellow plug on that yellow connector is for the side airbag and needs to come with it. If you don’t have a side airbag, the yellow plug needs to come with the harness, if you do have a side airbag, you’ll need to get the terminator plug from the dealer for both sides. Also, there is a seat position sensor shown in the picture below the harness that needs to be plugged into the harness. Without that you will get a DTC C1981, Front Driver's Seat Track Position Switch Circuit Fault. That sensor is in the front of the driver’s seat on the console side held in by 1 screw.

Passenger’s Side
Like the driver's side, you will need to connect the harness under the aftermarket seat with all of the sensors plugged into it. Here is a picture I took of the passenger’s side harness with the needed sensors.

PASSENGER’S SIDE HARNESS
· If you don't connect the seat belt sensor you will get DTC B2692.
· If you don't connect that yellow plug (side airbag terminator), you will get DTC B2295 and a LFC 23.
· If you don't connect the OCS Module, you will get DTC B2290 and LFC 16. You get the same indication if you don't connect the bladder.
The OCS Module is riveted into the seat rail. You will need to drill out the rivet to remove this module. The bladder takes some work to remove but is fairly obvious, you just need to remove several parts to get to it.
With my aftermarket seats installed, I currently have no DTCs and no warning lights with the airbags working properly. The only thing I don’t have is the use of the occupant classification system, meaning the airbag is always active on the passenger’s side.
WARNING: Following this procedure will leave the passenger’s side airbag active all the time. The airbag can be fatal to small children. Use this procedure at your own risk.
