Hey Joe. Your 2015 Jayco Greyhawk motorhome has two possible locations for the brake controller plug depending on what configuration your dash is. I've attached a couple of pictures below that will show you the location for either one. Please note that your motorhome should only have one if it came from the factory with a 4-way or 7-way connector.
To add a brake controller with a custom harness to your Jayco Greyhawk, I recommend the Redarc Tow-Pro Liberty item # RED49CR. This is a proportional brake controller that automatically adjusts your trailer's braking based on the deceleration of your motorhome. The Liberty has a unique installation method where the main unit is concealed behind your dash and the only part visible is the control knob.
The Redarc Tow-Pro Liberty item # RED49CR includes a custom fit wiring harness that is going to plug directly into your Jayco's brake controller plug for a quick and easy install.
What kind of trailer are you going to be pulling?
