I never touched the back of the instrument cluster or unplugged any of the wires on the instrument cluster .
Exactly! Check the fuses first. Also, some cars have the dash connected with the 'entertainment system', like some saturns for example, but I do not think it's the case here... Did you leave out any connectors that didn't fit the new unit?
