There is an orientation to the "plunger". A small tab on the part that rests against the inside (part with the key slot) cylinder fits into a small hole in that cylinder. I am not sure how rotating 180 deg would be enough of a change to make a difference. Since you found it was different I'll accept that.
To replace the center wire it is necessary to separate the cable from the lock cylinders. There is a ring with two indentions that can be rotated 90 deg. and allow the separation. Once that is done spread the two "legs" a bit so the the two contact bars can be slid out. One bar has the center wire soldered to a terminal. To remove and replace the wire it is necessary to remove the other end from the distributor and remove al the parts to see the brass ring (be sure to note the order of parts removed). A pair of needle nosed pliers or small punch can unscrew the ring and expose the final parts. Once all removed including the spring with copper mesh the end of the wire should be visible. When the other end is unsoldered the wire can be pushed and then pulled out. Reverse everything to replace the wire.
