tail light/brake/turn issues

temporarily powered up (no engine) my 69 swinger to check new harnesses, connections, bulbs etc, and the rear brake lights, tail and turns are screwy. front markers & turns are ok. No right tail lamp. Apply brakes, no right brake light. Left turn and brake, left turn and right brake comes on. Brakes and right turn ok. Grounds ok. Had the stearing column out to rebuild, and it seems like the turn signal lever makes things act funny. does power for the rear turns/brakes go through the column harness? did i screw up the turn signal switch, or get the connecters mixed up during reassembly
