The Turn B/U #16 fuse is fed from the ignition switch only when the key is on run or start, so if that fuse is hot with the key off or even with the key out, the ignition switch could be at fault. The airbag number ten fuse and the gauges number four fuse are also fed from the same pink wire from the ignition switch. So check if those fuses are also hot with key off and/or out.
If so, you may want to replace that ignition switch or look for a short to hot along that pink wire from the ignition switch to that I/P fuse block.
