Lights Out
I replaced all the exterior amber and red camper lights in front and rear. When I plug into my truck...none work. The porch lights and tail lights work fine. I wired everything exactly was it was with...

The lights are wired in parallel not series... So you won't have the Griswald Christmas light issue where one light goes out they all go out.
What is strange is that all the lights you installed are not working. These are marker/park lights and would be powered from the wire harness that plugs into the truck. If one or two lights did not work I would say they are bad or installed incorrectly. Since none of the lights are working I would start by checking the source. As others have mentioned, get a test meter and start at the plug that goes from the trailer to the truck. First check voltage between "Pin 1" and "Pin 4". Then check for voltage between "Pin 1" and "Pin 3". Of course make sure the headlights are turned on the tow vehicle while testing with the meter.
If no voltage found, look for a blown fuse in the tow vehicle. What year, make and model truck?
If you have voltage there... Then check for voltage at one of the lights you installed.
