So I did something similar... I used Anderson Power Pole connectors, (still overkill for what I'm running but I got them cheap) installed one on the rear & one in front. We were tired of connecting different equipment to the rear without a good (& consistent) way. Added the Anderson connector to the tractor which are fused & switched (with relay) separately from the rest of the tractor.
Now every piece of equipment has a Power Pole connector on it... I make the harness for the equip it will work with... Anderson Power Pole connectors are quite a bit less expensive than the connector you are looking at & you don't have to worry about ordering the male or female connectors separately (if you even can)... After the Power Pole connectors are wired they only connects one way so no issue connecting it incorrectly... this also makes it easier to have some spare connectors on hand being they are not gender specific.
This is the Power Pole Connector in the housing I used... (I made the bracket)
