having all 4 light circuits good is important for the signals to work properly - any old thing can happen if there's bad grounds anywhere - do your rear signals work? the harness itself might be fine, but you may not have gotten it in correctly, or there may be pieces missing, like the grounds or the connections to power points - is the circuit fused, and have you checked the fuses? does power come from the light switch and do the other light circuits work? do the front lights work as park lights?
