Our Enclave, which has the trailer package, came with a wiring adapter in the rear storage compartment. It consists of a plastic connector attached to several foot long wires. I first assumed that it was for the trailer plug but the connector does not fit the plug. Anyone know what it is?

I believe it is for a brake controller system for a trailer.

Correct.

If all you are going to tow is a flat 4-pin trailer, then all you need is the round 7-pin/4-pin adapter. About $10 at Walmart or $18 (12496599) at the dealer.
