73 CJ5 ignition switch question

This is my first jeep and first time posting. I have a 73 cj5 that has had multiple modifications. My key for the ignition snapped in half and I had to pop the ingnition switch out the back and hot wire it with a screw driver to get it home. I just purchsed the following ingnition switch

It appears to be a pretty straight forward change out, however I am concernd if the wires need to be plugged in ia specific way to the new switch. Any feedback would be greatly appreciated.

 

Switch and plug both only have 1 horizontal pin on them. Two outside pins on both sides of swtch are not used IIRC.
