Question:
I have a factory plug under my truck and I’m pretty sure I can just buy a harness that will allow me to connect a trailer can you help me with this?

Hey Ryan,
I took a look into it, but I'm not seeing a factory plug listed out for your 2007 Honda Ridgeline. If you can possibly test the pins to find out their functions and shoot me some photos of where you found the plug I'd be more than happy to take another look into this!
To add a 4-Way flat trailer wiring plug to your Ridgeline I recommend installing the T-One Vehicle Wiring Harness # 118400. This tees in behind your taillights so you aren't splicing into factory wires on your truck.
