airbag warning light....
with the help of threads on installing a Fuba rooftop antenna and new rear speakers on my 951, all work great together... but, now I get an airbag and seatbelt warning light illuminated (or not go off after start-up) on my dash.
I checked fuses and relays and NONE are listed for these two devices in the fuse box.
is there a sensor connection, or something like that, near the "radio" in the console that I could have disconnected during hook-up of the antenna wire?

I tripped my airbag computer when I had my gauges out to fix the lighting. I had to perform a reset using the diagnostic connector.
HEre is the page I D/L a while back:
13.7 How do I reset the air bag indicator in my dashboard?
The following applies to 1988-forward 944-series cars equipped with air bags. It does not apply to the 968. The 968 air bag light can only be reset using the Bosch "Hammer" diagnostic tool.
On the passenger side foot well, at the top under the dash, is a white "Molex" connector that goes nowhere. It has three pins in it, and the center one is the test pin. If you look at the end it will look like the following figure, with three holes in it. Inside each hole is a metal contact:
(sorry, figure didn't transfer)
Pin # 2 is where you must connect a wire and run it to the drivers seat. Connect a ground lead (for example, the metal door latch on the passenger door) from ground and run it to the drivers seat. You will do a series of connections and disconnection to the two ends of the wires to perform the Air Bag reset procedure, so go ahead and take a seat in the drivers seat and have your keys ready. Oh, you will need a watch with a second hand to count time. Remember that this is a German car so be punctual about your timing.
Procedure:
1. Engine off - key in off position.
2. Connect both wires - grounding the test pin.
3. Ignition switch on (run position) do not start car.
4. After 5 seconds disconnect wires.
5. Wait 5 more seconds.
6. Reconnect wires, grounding test pin again.
7. After 5 seconds disconnect wires again.
8. Wait another 5 seconds!
9. Turn off ignition.
Remove the test wire and try starting the car. If all went well you should see that air bag warning lamp extinguish in about 10 seconds (the longest 10 seconds in you life!). If that fails, try again. If it fails after the third attempt you will need to use a different procedure to "READ" the fault code to find out why the unit is faulted. That procedure is similar, but the fault codes are encoded and you will have to get them from the air bag service manual (WKD.493.621).
