Electrical problem involving ignition

I replaced the key cylinder and ignition switch. Prior to doing this, my vehicle had no problems starting until the ignition switch fell apart. After putting new key cylinder and ignition switch in place, I attempted to start the car. When I turned the key to the run position, no lights came on in the dash, I turned the key to start the car, nothing happened. No power to ignition at all. I tested the starter solenoid, which is relatively new, and it was operating correctly. It would turn over vehicle using two large posts, and the screw post to positive post. I don't believe I'm getting power from the ignition switch electrical harness to the ignition switch. I've been told there may be a problem with a fusible link. Also, I don't know whether a faulty clutch safety switch would result in absolutely no power to the ignition switch. Please help!
