the turn signals do work. so is there a separate output path for the brake lights vs turn signals?
Yes there are two sets of contact points in the turn signal switch for each turn/brake wire. When the switch is in no turn, the white wire feeds both contact points for the yellow and dark green wires. When either turn is selected the points are switched for that side, and the brake is disconnected so the turn light can flash.

Don't forget to press the brake for the white wire power test.
