I just installed the Blue Ox base plate and also bought their width adjustable tow bar. The entire setup was about $600+. Good stuff.
As for wiring just get three diodes and splice them in at the wiring running along the drivers side rocker panels inside the cab. Run the wiring to the tow vehicle through the firewall close by. No need to drill a hoe just pook through and existing spot with other wires. You can get the diodes from hitchsource. They are very easy to install. It is not necessary to add light bulbs to your tail lights!!
