need some electrical help bad
 

So i just got my 1990 rs 5.0, i really need some help. First when i turn my lights on i have no dash lights at all. Second, my brights work but i cant switch to my dims, the switch on the collum doesnt click when i try to switch though so that might be the problem. Third, when i hit the blinkers they light up but dont blink for any of them. When i bought it all of the tail lights had been taken out cause the assemblies were off so i found all the bulbs in the car, put them in checking to make sure they weren't blown but im starting to think they might be the wrong bulbs so if i could get the bulb numbers that'd help. Also my rear running lights are really bright while the brake lights are dim, its like its backwards? Any ideas will really help as im not a fan of electrical. Thanks
