In my 84 Cutlass(which was a Hurst from the factory), I swapped out the stock column for a Flaming River chrome column. Im going with the Flaming River push start sometime soon. My question is about the ignition switch. The wires on the switch are pink, red, purple and brown. I got the ignition wired to a Toyota Camry ignition(key and tumbler) using the red, pink and purple but cant figure out for the life of me what this brown wire is for. Any suggestions??
