There is a couple of yellow and blue connectors under the dash, steering column shield cover and under the front seats, also 1 of left side and 1 on right side of dash board somewhere. The control power and signal to airbag, do this with battery terminal negative removed for 20 minutes prior to this if you dig into connectors.
The dash comes apart with 7 and 8mm socket, or mini socket set. Driver side lower kickplate needs removed and then steering column plastics have a few hidden screws and unsnaps from clip near ignition if you squeeze the plastic housing together a little bit, it will unstress the clip and let you unsnap it easy by tilting a small mini flathead screwdriver in there to wedge it. then you will see the 1 yellow and blue connector to unplug, inspect, clean and put together. There is bunch of tutorials on youtube for steering column shield removal. Sometimes the wires get weird at the top and side of the column at these blue and yellow plugs that control the stuff on wheel and yellow for airbag connections. Good luck. If you have bad luck, it's probably the "clock spring" just underneath the steering wheel at top of column. Tutorials online for this..
--edit-- For dashboard stuff, I only use mini flathead, and mini socket set.
The mini flathead will come in handy for wedging the clips on the connectors, without breaking 'em..
If it's cold outside, freezing winter etc. Don't mess with the trim, dash, connectors or wires. Need a heated place for that stuff or things will snap easily.
