Dimmer Fuse in 95 Ford Tarus

i recently got a new car which obviously is a 95 Ford Tarus and i installed the old headunit from my last car and after getting it installed ive been having problems with my Dimmer Fuse constantly blowing on me and i was wondering if it had anything to do with the two wires from the old harness that are the same and from what the datasheet told me are both for the dimmer capability and seeing as i didnt use an aftermarket harness i was wondering if it had anything to do with thoose...this problem is really troublesome seeing as at night i cant see anything on my instrument panel

slightly off topiv man but perhaps you could tell me where you got your info to install your radio... i got a new tarus myself  ( '94 ) and it didnt even have anything attached.. i have an original factory radio for another tarus same year just no hook up yet. any advise?"On a long enough timeline the survival rate of everyone drops to zero..."
