I don't know about switching to a Caddi column, but i've done it three times with a truck column. I started with a straight stock column and had problems with the turn signal cancelling cam, along with grinding noise in column itself - so I removed it again for a tilt with intermittent wipers.
Its not "hard" persay. Just time consuming and knuckle busting. It tore my skin up removing the electrical connection from the column. The ignition is the little "L" shaped plug. The other one next to it is the headlight highbeam switch and the long skinney plug is for the wiper switch and all its functions. Then there is the stand alone cruise control wire. I think that's it for electrical.
Will the Caddi bolt to the same location under the dash? This is a crumple zone in case of a frontal inpact. The column will crush here along with the column itself (internally).
Can you post pictures?
