The switch is on the gearbox, But not sure of the exact location for your model. But guess there are not many other wired items on the gearbox.

SOURCE: Rear lights do not work, bulbs ok, fuse ok

You  probably have a frayed wire touching something metal (short to ground) check your wiring, check your grounds.

Very possible if they were from auto zone or cheap knockoffs,Best to have original rebuilt or buy buy factory alt.

SOURCE: Instrument panel went dead

Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).
