1989 560sel Mercedes Benz

I have a 1989 560sel (American).

I was removing the instrument cluster to clean the cluster and when I went to go put the cluster back into place the fuel, oil pressure, Temperature, and RPMs were all messed up.

The fuel was full, (when I know it is near empty) and the fuel light was on.
The oil pressure was all the way down, when it is usually up.
The temperature would go all the way up.
And the RPMs were only affected if I turned my bright lights on (in which case the RPMs went down)
All of the said instruments (oil pres, fuel level, RPMs, and temp) were affected when I turn my lights on.

Thanks so much for any help!
