Trailer Hitch Wires

My Tacoma comes with a towing package but there's no wire hardness that can be connected to the trailer. I'm wondering if you guys can suggest a set of good trailer wires and perhaps your easy to follow trailer wiring instruction? As always, thanks in advance.

A factory towing package includes a 7-pin connector at the bumper, bigger alternator, battery, trans cooler for automatic, and pigtail for brake controller. If this is a dealer installed "tow package", go back to the dealer if you don't have a trailer connection at the rear bumper.

 

One like this worked great for me: http://www.suspensionconnection.com...ing-kit.html?gclid=CJXB8qOgirkCFYuk4AodU3cAcg

I had a hitch but no wiring harness. Plug & Play, took about 20 minutes max to install.
