Short Circuit

I have been trying to trace the problem in my girlfriend's mirage for a week now. There is a short somewhere that is causing the fuse controlling the dash and tail lights to break. I have traced the wires as much as possible without removing any of the interior. There is a spot for a light bulb that doesn't have a bulb but that shouldn't keep blowing the fuse. When the fuse blows I have no tail lights or dash lights. I would like to get some advice on what to do next or at least find a wiring diagram.

I've had that problem with my 93 mirage.... since I bought it... I believe it is connected to teh radio wires/... did you recently install a new radio on the car.... I have wiring diagrams but currently trying to deal with one other prob.... check that and let me know... would like to get to the bottom of that for about 5 years now..... though the tail lights are not out..... but the interior 10 fuse will burn each time I stiall a new one.... let me know. good luck.
