I finally installed my SB I've purchased a few weeks ago.

First I went for the Option 2. Removing the side panel was quite easy but I couldn't unplug the the cable
from the sensor. Too tight.

So I went on with Option 1.
Also quite easy but be carefull: you really need a magnet to get the washer out!

Even with the second option I had quite some difficulties to unplug the cable but it did.
Next question was: how do I place the SB?
You can indeed plug it both ways and also 180° turned.
Happened to be lucky because first try was apparently the right one.

And then .... the test drive...
This SB is indeed quite a mod! No throtte lag and therefore a nicer accelaration!
The beast got mightier! I like the fatc that when I push down, the car reacts immediatly...

Anyway, I'm happy :-)
