Bought and Installed the Draw-Tite hitch Receiver. It was so simple, I won't even elaborate. It is a 30 minute job if you have a pair of ramps to raise the rear up, have a large socket set, and a torque wrench.
Also bought the aftermarket 'factory wiring kit' (comes with the factory plug to the 4-pin, and two relays) Again; laughably simple done in 20 minutes. If the relays get annoying- purchasing higher quality compatible relay will make the sound much less noticeable.
The most hilarious thing about all of this is the 'towing wiring' prep are just the addition of 4 ft of wire and two relays. Most cars these days need reprogramming to send power to the tow wires.This plug, plug, plug and play was a big relief.
I'll be towing my 500lb camper, along with an array of rental trailers to move appliances or general landscaping mulch.
