4 pole kill switch

[SCCA_racer]

I am upgrading my race car from a 2 pole to a 4 pole kill-switch. The switch comes with diagrams for a one wire or a field alternator style of installation. Difference being that one breaks the connection from the field wire to the positive pole of the battery with its auxiliary terminals while the charge wire is interrupted by the break in the main fuse block. The other interrupts the charge wire to positive pole only and omits the field wire. Am I missing out and this is just showing me how two different alternators will be wired? It would appear if this is the case that I need the field wire style. Am I right? There are two diagrams but NO instructions or explanations with this thing and I don't want to ruin anything or burn up my car before I get it back on the track. I have attached a pic of the diagrams.

Thanks

Bryan
