The fuse blows so there has to be power going to it at switch on.
If this problem didn't exist before inst' panel R&R, that's a clue to the location, Or...
Maybe the problem did exist and was only discovered after that R&R.
For example
The little orange wire does go up the steering column to the shift indicators bulb. If the ignition switch had been replaced with aftermarket and that orange wire put in the wrong connector position, that would blow the fuse. Seen that before.
Other common faults in the orange wire circuit are the ash tray lamp ( pinched wire ), and the radio dial lamp ( aftermarket radio hook up with elec' tape ).
