i recently bought a sunpro tach for my car and had it installed professionally. the backlight however is reversed with my other dash lights (as in as i turn the dimmer switch up the tach light goes out but the dash goes on, vise versa.) is it supposed to be like this or did they cross a wire? how can i fix it?

They hooked the tach light up to the wrong end of the pot that varies the dash lights. Take it back to them and make them correct it.

They hooked the light up to the 12 volt lead and the wiper lead on the dimmer pot. They should have hooked it up to the wiper lead and the ground.
Anybody can make that mistake. That's why anybody with half an ounce of "giving a damn about their work" checks it when they're done.
