No headlights, No Tach?!

Ok so i have a 1990 TSI, i bought from a friend. It needed to be bored, and the shortblock rebuilt when i got it, so i did it and added a big 16g. Finished the install, everything works great except the tach and headlights wont work. The dome light does come on, the fuses are fine, the headlights will flip up, but they wont light up. I tried a new bulb also, no such luck. Thanks
