Can you explain exactly what you mean, because I don't quite understand? So long as the two HT (thick) cables go to the two HT terminals (and I can't see where else they'd fit) then it shouldn't matter which way round they go. All that happens when you energise the coil is that the main contact closes and shorts the two cables together, allowing power to flow to the starter motor. :??:

I don't know about this particular relay but some relays have the hot side of the secondary winding tapped off of the battery cable side of the primary contacts internally. The negative is then used as the switch side make/break. If you have the cables reversed there is no positive feed for the secondary winding. That could be the case here.

Yup, putting the switch in the on position provides the ground.
That would be similar to interior lights in a cage. Opening the door lets the little button pop out of the door frame and provide a ground to complete the circuit.
