strange brakelite problem

[tc1959]

if the wrong filament is coming on it's either the bulb is in backwards or someone has reversed the wiring

Or one filament is broken and touching the other one.

im pretty sure its something I did wiring the new column.the old was a non tilt and the new was a tilt 3 yrs newer.right aeway I put it all together and the key worked backwards.then I found out (from you guys )that the tilt column uses ad different starter switch on the column.i changed it and the key works right now but the plug going into the switch had to be turned upside down to fit the plug on the switch on the column.
if I start pulling wires off of the column to see if this will go away where should I start?

thank you so much for the diagram.
i wont be able to look at it tomorrow.do you think its possible one of those 2 long connectors could be plugged in the wrong way?or are they keyed so that isn't possible.
as I stated before I had to put a starter switch from a tilt wheel on it to get the key to turn in the right direction.in doing so I had to plug those in flipped or opposite of what they were with the non tilt configuration.

just thought I would update you guys on this.i pulled both tail lites out.the side im having trouble with had 2 brand new looking bulbs in it.they had silver bottoms on them when the other side had brass.i switched all of the lights with brass bottom 1257s and everything is working as it should.
there must have been something wrong with the 2 newer bulbs even though the elements looked good inside and they said 1157 on them.
