radio installation

Yesterday i change the factory radio but the problem is i cant find the correct wires and i left it disconected and now when you open the door the inside ligths use to turn on and the horn its not working all the fuses are all rigth i check one by one and all of them are ok, is the radio interconnected whit the inside ligths or the horn, i have a 90 xj

Have you checked F14? fuse in the PDC in the engine bay?

let me check on that, i only checked the ones inside
