8 Pin round connector on Rallye dash

Many other models have this same round connector. The female terminals in them were oval shaped so the contact to pins was only 2 small lines. There isn't enough current passing here to require a substantial path. Factory never shoved it tight to the board either. I always found space to slide a pry tool under it.
Aftermarket replacement boards have shorter pins so any connector would finish closer to the board.
If you force it very tight then try to remove it again, and a pin lifts, the solder will peel the copper trace off the board. Explains why they weren't soldered.
Bottom line... if it isn't so loose that vibration would cause it to fall off, its good.
