Read several threads about these, but still have a few questions. Any brand reccomendations? any to avoid? im thinking a 48 tailgate strip for my 85, should it be longer? and the threads u read on this say to plug into trailer flights, but I don't have a hitch or receiver, so I'm assuming that I don't have trailer harness. what's the easiest way to this if I don't have a harness? the one I'm looking at has brake running and turn lights, no reverse. thanks guys!
