one question.

a rubber bushing. once you tighten down the screw/nut to clamp the 2 splitter pieces, the bushing really holds down on the cable.

side note: How many wires are on the 7pin side in the cable(inside the 7pin head on the PCB)?  and what color are they

thanx.

none. i removed the orginal coax cable.  there are only 2 connections in the original design (+ IN and shield).

shouldn't be too difficult to figure out which pin's output is + voltage to power the optical transmitter.

true but i'm lazy.  My worry is not figuring out which pin i need but having a point to solder it on to.  I'm gathering from your comments all 7(8)pins don't make it back to some sort of PCB
