electrical problem

whenever i shift into 2nd, 3rd, and 4th... the radio cuts off and the ABS light comes on and theres a click that comes through the speakers when the gear engages. also, it wouldnt go into reverse, i'm guessing something about the linkage. but i'm probaly wrong. its a 95 Si. does anyone know whats causing this and how i can fix it? everything is going wrong with my lude now, please help!

Does this happen when you do the clutch or shift the gear? May be a wire rubbing.

well it stopped doin it. but it was as soon as i let go of the clutch when it would do it
