The original style electromechanical flashers will still work if the terminals are reversed. However, it sounds as though you may be using an electronic flasher which needs power supplied to it's X terminal and the load to be on it's L terminal.

A couple common ways you could fix this: (1) Unscrew the fuse box from the firewall, pull it out, and separate it from the inner half of the bulkhead connector. That will give you access to the back of the fuse panel and allow you to extract the terminals from the turn signal flasher socket section and switch their positions. (2) Buy a 'reverse polarity adapter' ... They're a little round disk that plugs in between the flasher and socket to reverse the connections (basically just a more compact version of the fix you're already using).

Thanks for the info. Can you still get the original style flasher? The only I got was from autozone. It’s still a 552 flasher but it’s a lot bigger so I’m getting there is a circuit board in there. I pulled apart the fuse block when I fist discovered it and was going to swap the wires as you described but the terminal that has 12 volts is getting it via a jumper wire from another terminal from a different slot.
