We have a 2005 Boxster S. He has issues with the ABS, PSM, and the steering lock. Terminals 15 and 50 come up. PDF's would be great! The relay board does not have any labels on it either. One of them is clicking and causing a battery drain. When we swap the relay, it keeps clicking. That tells me that the fault is in the circuit controlling the relay, not the relay or the device. The steering lock is intermittent as well. There was water in the front well under the cowl area, and that may have caused some issues with corrosion.
Is there a diagram showing all of the grounding points? This car came from the coast of Florida, so we were going to clean the grounds. With terminal 15 and generally strange issues, I suspect something fundamental. It is going to be a challenge to sort it out. I have already lost most of my hair, but may pull the rest out before this is over.
Thanks.

Thank you very much. This should help a lot.
What is MSW?
The ABS system has faults too.

I don't know if this is still needed or active, it's been a little while, but I was able to find wiring diagrams for the 987.1 and .2; they're out there on the interwebs with a little bit of googling.
If you still need something, I can figure out how to send you what I've found.
Good luck

Thanks. We found a broken connector housing under the steering column, but he got frustrated and sold the car before we found the root problem.
