honda accord 98 ex lost dashlights

lost dashlights and dimmer control, hooked a new system in it and a week later lost dash lights. it's wierd the clock light is on when the headlights are off and they turn off when you turn on the headlights. tried everything from fuses rewiring the radio. a schematic of the grounding and wiring would be great but i can't seemto find one any help would be greatly appreciated
