I don't know about a 62 but here is the color code GM has used for years: light blue--left front T/S, dark blue--right front T/S, yellow--left rear T/S, green--right rear T/S, white--brake light feed, black--horn, purple--12v feed. On unknown columns you have to find the 12v feed and then experiment with what happens when you move the T/S lever to it's different positions. A second wire when voltage is applied will cause both the R&L rear T/S wire to light the test light when the t/s lever is centered--this is the brake light feed wire from the brake light switch. With a test light and 12v jumper probe one should be able to figure out ANY column in 30 minutes.
