F.A.S.T. Install
 

Hi All
I recently got my hands on an operational GTS with a F.A.S.T. system to be parted out, the owner(my cousin) said I can have as much parts from it as I want, for free, before he junks it, the entire F.A.S.T. system is operational in the soon to be junked car
So, I was wondering if anyone can help me with some info on how to put a F.A.S.T. key into my non F.A.S.T. GTS? Maybe someone has done it before? and is it worth the time?

Thank you :)

Regards,
