12v Wiring - Still Confused

I run the running light wire to each light from the front J box. It's easiest to run the wire across the front of the trailer to connect the two front lights. Come up the wall framing from the J box to one light, then across to the other.

Adding a second J box at the back allows access in case repairs are needed plus makes it easier to run the wires. Run your tow wiring from the front J box to the back. From there, run the green running light wire to one tail light location, then across the back to the other tail light. From each tail light, run to the side clearance lights.

You can see the wires coming up from the back J box, to the first tail then across to the other tail. A small chase hole runs the wire to the clearance light.

I use electrical wire nuts to join the wires at each light. So, you would have wires joined at each tail going to each clearance light. Wire nuts make for easy access and repairs. The smaller orange ones work well in most cases and are easy to poke into the cavity behind the light. I frame around each light to provide backers for the light mounting screws.

If the light body is big enough, you can wire nut the wires in the lens space as well.

PM me for my email address and I can send more photos.

One green wire (TM for Tail and markers) coming into the back J box from the front, plus the other two tow wires. (RT, LT and Ground) One green wire going out to the L tail light. It's is joined with the L clearance light and the right tail light.

In the pictures, you can see the one green wire coming up to the tail light. The red wire is the left turn wire. There is also a brown wire for the right turn. It doesn't show very well in the photos. Most people run a white ground to each light as well; prevents future grounding issues.

I use the cavity behind the tail lights to join the wires and stow the wire nuts. In other words, the cavity is another J box. I hadn't framed the light mounts yet in the pictures.

Please PM me for photos. My Flickr account is limited.

Thank you!!  This is what I needed.  Yes, I'll message you for additional photos if you don't mind.  I like to see pictures and so far none that I have seen address exactly what I'm asking, mostly because I don't know how to properly ask it using the correct terminology.  

This is exactly why I love VTT. Somebody is unsure and yet unafraid to ask a "stupid" question that no one here would think is actually "stupid". Then someone more knowledgeable steps in to provide some clarity. No judgement, just helpful info. Thanks to all.

Nobody is a fool who seeks knowledge.

The first time I do anything I’m nervous.
The second time I’m confident.
The third time I’m feeling smart.
The fourth time I’m often bored.

The first time is always the most fun.
