http://s31.postimg.org/9r8etitxn/20160422_205134.jpg Just bought this truck and it had been running fine for last fee months, but every now and then this connector has to be wiggled. It's as if I have no power, but when wiggle it will allow the truck to turn over and start. The connectors need to be changed out I know and will do, but what is the box? On top of this my battery is not charging. I assume it's the alternator. It sat for 5 years and has a new rebuilt 318. I replaced battery and only drive on weekends.
