Is it possible to fix the 5 pin adapter for my te stick

i was trying to add a spring to my te stick but when i put it back together the joystick didnt work. i looked down and saw a wire coming out of the 5 pin harness.

is it possible to get the wire back in there? can i take the white adapter piece apart and try to recrimp the wire in there or can i go to radioshack or something and just get a new harness or something?

if you need a new harness I have a brand new, never used Sanwa wire harness WTS for $8.00 shipped.
