So I took off my dash to fix some minor things and when I put it all back on and turned on my car, the tachometer won't get any response from the car. It turns on and all the light are lit up. The rev limiter is not working, the buttons on the right of the tachometer to manage the gauge in the center doesn't work. There's only one connector that hooks up to the tachometer and I don't understand why it's not reaping to commands. Any tips would help. Thanks you
It works but it's not getting any response
