1991 300TE US non-4Matic.

There is a blue round plastic cam inside the steering lock which operates the cable going from the steering lock to the shifter. Can someone explain how it gets positioned/timed?

Thanks,

Are you talking about the position of the steering lock? I found a pretty in depth DIY on an old thread: DIY Ignition Switch/Steering Lock R&R W124
...Though they don't seem to describe anything blue, they do go into mention about what position the switch needs to be in. Perhaps it could lead you in the right direction

Thanks Matt, Figured it out but it's hard to describe the solution. I had to purchase an online manual which helped. This blue cam is for 90-95 only, it prevents the shifter from being moved out of Park unless the key is in #1 or 2 position and another cable requires the brake pedal to be applied.

If I had known the cam was in there I would have watched for it to fall out, my mistake. Purchased the parts from Pelican...Pelican could consider including instructions as they did caution not to turn the steering lock before the ignition switch was attached.
