ok my fuse that controls the signals and reverse lights keeps blowing out the first time i put it in reverse any ideas y this is happening?

 

For starters, take out both of your reverse light bulbs and look at them. What you will probably find is a broken filament that fell and shorted across the input wires causing enough current flow to blow the fuse (and not light up). If this is the case, replace the bulb-actually, better to replace both at once. If it blows the fuse with the bulbs out, start looking for frayed insulation on wiring.
