the starter is PURPLE and the ignition is PINK

Both wires can be found at the ignition harness.
Remove the bottom cover under the dash and look for the harness comming out of the steering wheel

The wires R up high on the steering wheel column. U will see a metal rod that moves back & forth when U turn ignition switch. Follow that rod down the column to the actual Ignition switch.
Ther R NO wires attached to your Key Switch in the column
