[Harp-L] g/bullet element wiring

["hazcon" <hazcon@xxxxxxxxxx>]

Hi all am looking for some advice on how to wire up a G/B.
The one i have got hold of(rare as rocking horse droppings in NZ) is a early 
nineties mexican 520D(no volume control)
The lead has been cut off so i just have the g/b body and element.
The element has 3 wires ,one side is a relatively thickish black wire and on 
the other side a same gauge red wire.In between these is a much thinner blue 
wire.
            I realise that i will need a shielded cable with the shield 
attached to the body but where does the blue wire go and which one is the 
high impedance,red or black?
The Data sheet i got on the shure site only mentions a white and a 
black(plus blue) cable.Anyone familiar with c/magnetics with a red cable?
TIA
