Wiring and Alarm Elimination

[nimblemotorsports]

So I have converted my 97 Boxster to Electric, and now the challenge is to change
the car wiring to adjust for this lack of an engine. I also need to change the guages so rpm is the electric motor rpm, etc.

I could really use the wiring diagram for this car.
A search shows mostly no responses to questions about it, and one or two links to sites that don't exists, and one saying it requires thousands of dollars to access the Porsche software. Is that really the case?

I have no ECM, and want to just eliminate the immobilizer box, which I understand also contains the lock controls. I plan to eliminate those.
The racing cars surely don't need this stuff also, a search showed some wiring reductions, but no details.

All I really need is a wiring diagram and I'll figure it out!
