FWIW, in my 1989 gt I used the red with light green stripe as a switched 12v source. It is in the gray plug by the master cylinder. I used one of the blue splice connectors to make the connection. I second Jester about the pickup wires. Do not use the white wire. I can't tell you exactly which wires to tap into at the distributor though. You can look at some wiring diagrams on MSD's site if that helps.
