My fuse for my backup lights keep blowing. Whats going on?

light wires are fine. I put a new plug into the transmission less than a year ago, but yesterday I unplugged the plug-in that goes in it and put a new fuse in, put it in reverse and tested the plug-in and it was getting power, but if i was to plug it into the plug that is on the transmission it will blow the fuse. So is it a bad plug?

yeap.sounds right,short somewhere in there.what is it for?

Whats the plug for? It is screwed into the transmission, when you put vehicle in reverse it sends the signal to turn on backup lights and backup beeping and such.

fixed now?

have not had time to try. ill get around to it.
