This shows an add-on signal mechanism, but the color coding for the wires is the same as the late R, S, A, etc., Internationals.
It has six wires at the column. Assuming you can still see the colors, red comes from the stop light switch. Black goes to the flasher unit. Brown goes to the left brake light. Green goes to the right brake light. Gray goes to the right front turn signal. White goes to the left front turn signal. Tail and parking lights would be the dimmer filament on the 1157 bulbs front and rear, and the six from the column, wired that way, should give brake lights in the rear and turn signals on all 4 corners on the brighter filaments of the bulbs. For the indicators on the dash, it would be a splice into the gray (right front) and white (left front) wires. If you can't make out the colors on the wires from the column, there's a process of elimination to determine which is which, and I can dig that out for you. I think.
