Putting new ignition and column lock in my 1984 300SD.

Lots of problems.

1. Kept the 2 vacuum hoses on the housing, but the tubing came out of them.
Which one goes where? I think one tube has a stripe.

2. These tubes have oil ( in the switch too ). How to fix that?

3. Can't remove the plastic piece ( for key buzzer ) off the old housing.
How do you remove it?

I hope after all this, the starter, heat & ac, and blower work.

Thanks.
