The orange wire supplies voltage to those circuits..so the orange wire is broken somewhere or it's fuse is blown. Check for voltage at orange wire terminal on H/L sw. Check voltage, in and out, of tail/stop/dome fuse. Your dome light is probably not working either. Hot RED comes to that fuse, thru fuse and out to Hot ORN. Hot ORN branches to dimmer and to H/L sw where it energizes BLK at switch "on" mode.
