strange... well according to the diagram you posted in your first post.. my car is wired just like that.. except the 2 pins from the relay ( 2 + 5 ) actually go somewhere.. and arent just empty like that. i dont have lights being powered right off of my Central lockign pump. Maybe its different from roadster to coupe... where is that first diagram from?

Your dilemma is very confusing because as you said.. all the modules are comunicating...but no vacuum is being sent. The only thing even remotely close is the Sentry Key Antennae ring thinking the key is too close to the cylinder... but even if that were true, the lights would not flash. And what makes it even more confusing is that it still locks when you drive and open the door........
