Hey Joe,
Get get your hands on some manuals, as I said above. What you want to do will be alot easier if you get some knowledge of your basic wiring. If wired incorrect there can be all sorts of headaches, not the least is a fire and the incineration of your truck, ( whether it's towed or not.)
Maybe get in touch with a local trade school or high school or community college that offers auto tech courses, ask them if they could use your rig as a learning tool, maybe let you stay for some instruction.
It is almost impossible to be directed on a forum to assist you in what you want to do without risking a serious problem. ( I have witnessed more than 1 bad wiring "carbeque").
You need to do some homework....just wanting to know is not going to make it so.
