Muh Stang

I'm having a problem with the ignition of my mustang.
I believe the problem exists in the line some where between the ignition cylinder and the plug in that the white and pink stripped wire connects to the brown and pink wire. if I use a jumper wire on the white/pink wire(Starter) to the positive terminal, my car will start. but if I leave the connection in its plug-in under the fuse box nothing happens when I turn the key. I checked the fuses and relays and all are good and should perform correctly. I'm at a loss and any help given will be much appreciated.

How did you check fuses? Visual or with a multimeter, sometimes fuses get hairline breaks in them that you cannot see by eye.
