not to sure if everything is working yet. I picked the car up cheap and am just starting to dig into it. I know that one of the wires that isnt plugged in had a jumper in it, and the other wire is just there, it is just a white wire. My father said , from what he can tell from some wiring diagrams, it looks like both wires are in some way involved with fuel, i think he said one had to do with fuel cut off. Just not sure why the one would have a jumper.
