It is a tuneable coil. You change the inductance by screwing the slug in or out of the coil. As for the hookup, most likely only 3 pins are used, the other 2 are for stability. Do some continuity checking to see what's what. I cannot tell you what the value is, you'd have to measure it with an inductance meter.
