Putting car into reverse blows turn signal fuse

[Jason]

Everytime i put my car into reverse it blows the 15A turn signal fuse under the steering wheel, ive disconnected the wiring from under the gear shifter and it still blows, i havent unplugged the loom for the tail lights as i thought that would be pointless as its already been disconnected at the front.

I dont know if its related or not but the day before i completely took my dash apart to remove my head unit and install a sub and amp.

Any suggestions of what i should do? Do you think it could be in the tranmission, should i disconnect it and see if it blows? maybe move it around to stop shorting?
