What is the car you are swapping in ? might help with some details along with what engine, harness and other details.
It could be the 12+v wire to the Coil for full 12+volts on start up.. maybe Tan in color !? you don't need it.
You should be able to get some Russell (or other manufactors) adapter for the power steering box and pump. O-Ring or Inverted Flare to AN fitting and then use some SS Teflon lined SS Braided hose.
Most of your local speed shops can order what you need if they don't already carry the parts.. if not, I got my adapters and hose from Summitracing.com http://www.russellperformance.com/au...ose_ends.shtml
