Does anyone know where the factory plug is? I ordered the trailer package and never used it yet.

there is a detailed thread on this topic but here goes There is no plug from factory but the harness is taped to rear harness on drivers side about even with rear of rear tire look for a buldge in rear harness and pull 4 wire lead down and out and install the plug that you need

If the plan is to tow any of the new boat trailers, they now are largely using disk brakes, and the surge brake system uses a 5th wire connected to the backup lights. It activates a solenoid in the brake system which bleeds the brake system and allows it to back up.
