Sounds like a short in the wires somewhere. you will need a diagram & have to trace them.
Check if all fuses are working and see if there is any circuit short. Also check if the ignition switch is in a proper working condition.
If a 1987 Chevy Suburban has lights and horn, but no ignition, gauges, radio, or interior lights it could be a ground wire problem. It is possible that there is a short somewhere. Also check the dome light for a possible water leak in the headliner.
