That's correct... the plate lifts up (spring-tensioned) and there's both 7 and 4-pin connectors, which are the factory plugs, just mounted in the C4 bumper. I've used the 4-pin many times for pulling trailers. I don't remember using the 7-pin. I will occasionally dab a little dielectric grease on the terminals to make sure they're never an issue
