Thanks Man! The wheel came from my wrecked M5... but what a PITA! It usually goes easily enough - just not this time.

First I had to disconnect the battery on the X5 - MOMMA! . Then I had to reassemble the wheel as I need to transfer some needed parts over.

Then... I over tightened the little screw for the ground wire and had to go fish around for a suitable replacement. After all that, I reconnected everything and the Horn would stop blaring. Turns out I had over tightened the three Torx head bolts that hold the horn plate down - so... I had to disconnect battery again and re-do the whole thing! BAH!

At least now it works! Thank Goodness!
