Help installing 791 bypass module

Hi, I ordered the bypass module and am waiting on it to come in. I was looking at the installation diagram and noticed you have to wrap the wire around the key cylinder. Does anyone know if I will need to take the cylinder off to install it? If so, how do I take it off? I'll include a picture of the diagram.

 

When I did it on my STi I did not have to remove the cylinder. Its just this rubber circle thing you place around the end of the cylinder near the key.

 

Also you know you have to put a key with a transponder inside the module right?

 

Ok, thanks. Yes, I'm aware of that, but thanks for making sure I knew. lol. From my understanding, if you don't put the key inside, the truck will lock down and you have to tow it to the dealership to have them fix it, right? or will it just not start? (just curious)

 

In that instance it would just fail to start. Same as if you tried to start it with a blank cut key. Are you installing the whole alarm yourself?

 

Oh ok, well cool. Then I shouldn't have to worry about expensive fees if I somehow make a mistake with the wiring.
It's a actually a remote start system, but yes, I'm installing it myself.
