This should be more than enough information for someone with a bit of an electronics background. Sorry, that is about all the info that I will share, as this kind of work is part of my business...
I am in need of having my immobilizer repaired. 2000 boxster Car starts and runs OK, convertible top is OK my windows do nothing.
