A few specs from an Infinium 10x5 Eliptical Power DD coil.

From front face of plug which is stepped in shape.
Top left exposed pin is Green
Top right exposed pin is red
Lower left pin socket is Black,with screen an Foil wrap to this.
Lower right pin socket is White.
Yes the 5 core coil cable is foil wrapped in the sheath an cable has polycore twine reinforcing for added strenght an stretch resistance.
The Metal of the plug housing an knurled ring is not connected to anyscreen wire or other.

a few spec from an Infinium 10x5 Eliptical Power DD coil.
5 core cable
White to Brown of coil half one
Green to Brown of coil half one
Red to Black of coil half two
Black to Black of coil halve two
Screen wire connected to the two halves of coil shell (two halves of coil shell are Electrodag coated/painted)
the Brown coil is 26T light duty tin plated multistrand hook up style wire pvc coated
the resistance of this coil 0.9ohms
the black coil is 40T light single strand Kynar wire.
the resistance of this coil is 7.4 ohms (with no resistor across)
internally across this black coil wired in parallel is a 1/4w resistor 680
color code,blue,gray,brown,gold.
At this time i do not have the inductance values for these individual coils,but these few spec gives you the essential towards this DD infinium coil
Note the coils are wound bundle style an heavy hot melt glue bonded to a foam eliptical dd shape former.in an original.this foam former is not electrodag coated only the two coil shells.
there is no epoxy in these coil shells ,only great quantity of hot melt glue bonding.
hope this helps those that may have an interest towards built their own?
as time allows will try to post some photos of the actual coil shells an windings exposed.an you will see no high science here?for the Infinium coils.
