Speedometer not working, accelerating weird now

I have a 08 galant and was messing around with my stereo wires and the next thing I know is that the SRS light is on on my dash, the speedometer is not working(lights work fine), the odometer is not registering new miles, and the yellow shifter light on the dash that illuminates whether you are in park drive neutral etc. is not showing up either. They are all illuminated with the blue lights but the yellow indicator light is not showing up when I shift to drive or reverse. And the scariest problem of all is that the car is accelerating weird when I drive. I'm almost positive it had to be something I did before fiddling with the wires behind my radio because these problems only arose right after. Please help I am not very car savvy at all. My knowledge is minimal. Thank you for reading.

Did you ever figure out what the problem was?
