Generally pink is hot "in" and white is output. Just remember "hot pink" . pull apart the ts/brake harness electrical connector coming out of the steering col and the "white" in not the col half but the other half will be hot w the brake pedal depressed (this is the other end of the previous "white" wire. If good there w your VOM see if you have continuity on the other (the column) half of the connector for this white wire (it may "most likely does" continue on as white but check the colors in the wiring diagrams at www.mymopar.com to find out) and there's 2 wires in that same col connector half which will be the 2 out wires to each brake filament and will be hot w the TS stalk in the neutral middle position and the brake depressed. If so continue downstream toward the rear starting at the pull apart connector in I believe the drivers kick panel & if hot there (brake depressed) then there is one or 2 more pull apart connectors going toward the rear. W both lights out it most likely is an input prob rather than a ground since less likely that both sides would lose their ground at the same time and I forgot in your post if the flashers are good but if they are then the brake lite grounds are good also.
