Can't Identify two wires on 1970 Mustang ignition

I am wiring up an after market ignition under the dash and have identified all but two wires. There is a small lvender and a small black wire that I can't seem to identify. All I know is they don't like juice being run into them as they spark like crazy. I tried looking at a wiring diagram but, just can't seem to wrap my brain around it. If anyone could help me out it would be appreciated.

Is there a large ring that goes against the key switch where it goes through the dash? If I'm not mistaken the wires your talking about are ground wires that attach to that ring. For them to spark when you apply voltage to them would mean they are grounded.
