Try here, look under body electrical or wiring diagram, you should be able to trace what wire goes where.

At the top of the wiring diagram section is a code breakdown. In your example, the Green/White wire powers the switch via the 20 amp stop fuse and the other wire, White/Green takes the voltage from the switch when the brake is depressed and passes it to the bulbs in the rear light housings. To explain it further, G/W means Green wire with a White stripe on it. B is black, L is blue, R for red, G for green, W for white, O for orange, Y for yellow, LG for light green. So, B/W would be a black wire with a white stripe. R/L would be a red wire with a blue stripe. Hope this helps.
