radio anti theft problem

it is all original wiring, never been played with.
okay this may sound really dumb but where is the fuse box? and which one should i replace?

i know theres 2 fuse boxes one under the engine bay and one under the dash? and which one should i replace? is there numbers on the fuses that tell me what is what?

im so noob :frowning:

on the cover of the one on the left side foot panel area, there is a cover over the fuse panel that lists out which fuse goes to what.

simply go through it, and search till you find the one reading “stereo” or “radio” and find it by comparing the diagram on the plastic trim, to the fuse layout on the box.
