anyone know what wire in the steering column is the +12v for the rear reverse lights?

i want to make mine work
converted from a 403olds/auto to a 400 pontiac with tko3550
i can use the trans as a switch to activate the lights (plug on side of trans)
just wanted to see if anyone knows what wire
there was the reverse linkage on the car at one time that would trigger something on the column to complete the circuit

thanks
