Thanks to everyone who offered advise on this. I got an meter and did find that any combination works for the 3 prongs. My flux is installed and working fine. I did install an in-line fuse from the battery to protect the system from the 1.21 gigawatts that this sucker puts out! I wasn't able to install the other switch on the passenger side "dummy" hole because I have a wiring harness running underneath it that prevents the switch from fully inserting into the hole. I tried numerous times to move the harness but it seemed that the only way to really get to it was to remove/raise the center console and re-position it. I wasn't up for that task as it's still a bit chilly here in Maine.
