So I gather this LFB solenoid is triggered by a relay receiving a signal from a 60C temp switch?  I assume the temp switch is located on the coolant neck either on the side or end of the head.

And so, by having it disconnected the solenoid is open leading to increased HC emissions when cold. Activating this solenoid(via temp switch) would decrease HC emissions when cold, and then would open the solenoid once warm restoring it to its "normally open" state. So, if I care about polluting, this solenoid will need to find temp switched controlled power. Is that correct? It was not connected under the PO. Is

Thanks for the diagram and explanations!
