Hmm, if it blows only if hooked up then pull out the lamp, and take a quick look at the lamp and make sure that the bulb didn't pop off it's seat touching both terminals. Then probe with test lamp on the terminal with red/green wire and the ground (the battery is right there) if it lights up, then move it the range of the hinge. Look at the plug and see if the plastic cover isn't broken, these tend to rot off and touch things they are not ment too.
Just another thought, what way do the wires face, to the passenger side or the drivers side. If they face to the passenger side there could be a chance that the ground switch is touching the power wire.
Try these, if this doesn't work we will go deeper....
P.S. Don't forget to replace the fuse before testing... Been there, don't that.
