I have the same issue, and found last night, that one of the wires was broken right at the clip. Not enough wire there to make a decent connection. I took the female connection part out of the plastic housing and spliced it as best I could. I could not find my soldering pen ANYWHERE so I'm picking one up on the way home.
Anyway, due to the shortage of wire, do you guys know of anywhere that sells the plugs with a couple inches of wire on them? I would like to use a new plug all together.
