Fuse Issues!

i have a 1993 oldsmobile cutlass supreme SL with the 3.1L V6, and i keep blowing fuse #2 in the fusebox thats behind the glove compartment. Any ideas what can cause that. I do have an aftermarket stereo, but i never had any problems before, and the stereo itself has its own 15 amp fuse. I do have one wiring change that i did that is on that circuit, but it never gave trouble before, and all the wiring looks perfect. The fuse that keeps blowing is a 15 amp by the way. I have no idea where to look

And what is in the circuit for this fuse?

it says INST i checked my manual says it covers, radio & clock, DID, passive restraint, passive restraint timer. and thats what i remember off the top of my head

Ok so follow the wiring in the affected circuits looking for a short or disconnect the included components one at a time to pinpoint the short, no magic bullet here, strictly circuit tracing.
