Three strange cables

[Enrique Claure <spanlab@ceibo.entelnet.bo>]

Hi Listers,  I am tidying the cables in my engine bay. There are three 
cables connected to a female plug. Cables are WU (white blue), WB (white 
black), W(white). My Haynes diagram shows these three cables
connect to the distributor. Both my old and new dizzies have only one black 
cable coming from the side.

WB  is lead from the coil
WU  right side of the dizzy resistor
W left side of the dizzy resistor

where and how do I hook these cables?

Thanks, Enrique
