If you have a temperature reading your OBC is on. If not, then it is not on.
Also, the OBC is the wiring of the car under the drivers seat I would highly recommend you do not remove it. That would be very bad because it would disable the entire car. The OBC is not one module.
I did the OBC, it was the best $50 I have spent on my Boxster. And try searching for OBC there are a lot of threads on this.
Welcome to the Forum!
You should post some Pictures!
And Good Luck with the Mod!
