pulsar problem

I'm new here but I have a question about my 89 pulsar. This probably isn't the right thread but I need some help. I am continuously blowing the fuse to the brake lights. I thought it was just a short but, I temporarliy fixed the problem by running the memory lead from a stereo to the brake fuse. Weird huh. I met another guy with the same problem on his 89. That is the only thing wrong with the car I really like the pulsars(especially with gas prices now). Anyway, is this a common problem? Is there a quick fix for it, or do I need to re-run the brake wires? If anybody can help I would appriciate it.
