4KQ Wiring diagram question...

[Quattrospg at aol.com]

I'm looking at the wiring diagams for an 87 4KQ in the Bentley and I'm trying to figure out which of the current tracks in the fuse box has power only when the car is running (when looking at the general wiring diagrams the upper portion of each diagram in gray is the fuse box)

Is it 30, 15, X or 31?

It seems to me that 30 has power all the time, and either 15 or X have juice only when the car is running..


Thanks
