wireing harness for trailer lights

Putting on a trailer hitch. Anyone know how to hook up the wireing harness? Someone told me that i can just plug it in, in the trunk somewhere. I looked and think he's full of sh*t. Any advice would be helpfull. Thanks

you can put a trailer hitch on a cavalier?

Yep, believe it or not they actually sell them. You can tow up to like 1000 lbs with an automatic, they don't recommend towing with a 5 speed. Places online probably sell a plug and play wiring harness that does indeed just plug in. Thats what I used on my father's Dodge Ram.
