1988 Honda Accord Rear running tail lights

I clipped the harness to the radio to install an after market Sony radio. Now I do not have instrument cluster lighting and rear runnning tail lights. Is the radio harness connected to the instrument cluster lights and the rear running tail lights? I do have brake lights and turn signals working properly. I am soory that I cannot donate anything being that I am unemployed now for 8 months. The radio was given to me by a neighbor.
