I am having trouble reading the schematic, and the top won't go down, I guess, because it thinks the trunk is not locked?? ( 2006 Roadster convertible)

So the mouse chewed more than the pneumatic line, I guess.
You are having issues with the diagrams, probably, because the names of switches and modules is stupid. (See red text below.)

The Electric Lock on the trunk is operated by the Power Top Control Module (PTCM). There are four wires going from the PTCM to the lock: Motor positive and negative as well as the locked line and the unlocked line. The PTCM MUST see the status change and be a valid "Lock" in order to move the top.

Look in the wiring chapter of the service manual under "Power Top" for the "Trunk Latch Assembly", that is not really the latch that is the electric lock. The ACTUAL latch sensor is separate from this, it reports a fully closed trunk to the CLP/SSM and the CLP/SSM tells the PTCM that the trunk is fully closed, once that happens, the PTCM commands the electric lock to lock, once the lock indication comes back from the electric lock, the top cycle can start.

I started a BIG project and posted all about the Top Sensors in this thread:
https://www.crossfireforum.org/forum...p-sensors.html
The intent was to empower people to understand and fix their own top issues. Problem is, everyone expects a quick fix these days and refuses to put forth the effort to learn, so it has proven to be a waste of time where most are concerned. Maybe you will actually read thru it and use it.
