Yeah, that was my thinking, but there was no continuity between W and ground when I tested it.
I'll get a globe and check just in case.

You should have NO contontinuity until the ECU tells the W point to earth...
The ECU controls the W point, when a problem arises, it turns it on (By earthing it), so with the 12V +ve constant on a light, and the other side conected to W, the only time the light will come on is if the ECU detects a problem and throws it to earth.
Most ECUs only earth things, they do not actually send the power out, the +ve is from the battery, and the -ve is controlled via the ECU...
So that, when you check for continuity, you will not have any, unless the ECU is saying you have a problem...
