Looking for a brake/tailight arm and light assembly for a 1930 Durant.

Just to let you all know, I found a tailight arm with the light assy. attached. I also found 2 really nice lenses with chrome rings from same seller. I am in process of installing same on the right rear fender for brake/tail/turnsignal lights. Would someone have a skematic of wiring up turn signal lights on these Durants using the existing lights without adding another bulb just for turn signals?
