Tow lights wiring?

I just put one in a few months ago. You can buy ones that just plug in at pretty much anywhere. I got mine at a boat shop for under $20.

In the very back of the passenger's side there's a plastic cover that is held in by plastic plugs. Upon first inspection it didn't look like there was any access, but they pop out pretty easily, and you just unplug the brake lights plug and plug each end into the hitch wire. You'll probably want to have a few tie downs when you do it, because there isn't really any intuitive path to run the wire to the hitch. Just be sure to keep it away from the exhaust.

Good luck..
