Guys,I am installing an American Autowire Classic Upgrade kit#500560.I have to tell you this kit is every thing you need.It is specifically tailored for these trucks.It is complete from bumper to bumper w/all connectors included.It is simple to install as it is setup to install in stages,w/individual instructions for every stage.What is cool about this kit that I liked is that it can be installed as a stock install but has plenty of room incorporated into for future addons i.e. a/c,pw windows,pw seats,etc.Has plenty of wiring for custom install as in routing the way you want to.This thing is complete,it is the most complete kit I've found.I also saved about $100 bones getting through this guy on ebay.the link below should get you to it.Hope my 2 cents helps.
