Now I wonder about that engine running signal... Somehow it will be even more suitable than just ignition, if it does exactly what the name suggest. But that reference to ground is to be checked. I suppose testing with a multimeter would be the only way to go.
I'll keep you posted, thanks.

If I understand correctly, it means that:
* If the engine is running, the connector is a ground point
* If the engine is not running, the connector is isolated, not connected to anything
To get a +12 which is active only when the engine is running, you should combine a permanent +12 and this "engine run ground" using a relay. There is a diagram in the BEMM.
