You may want to check to see if your tow vehicle is actually energizing the center pin...which is the normal backup light connection point... Here are the pin arrangements: https://www.etrailer.com/faq-wiring.aspx

I never saw a Big Valley WITH backup lights. :) Since they were all originally built with a 6 pin plug, they center pin Paul mentioned won't likely be an issue here.
As a rule, they ran any interior lights off of the marker light circuit and did not have an accessory wire in the trailer. Common with many steel trailers from Arkansas. So if you have a loading light, check to see if it powers from the marker circuit.

I haven't either......but if the guy says he has them...I just tried to point them at one problem I have seen...in general, many installers do not energize the center pin on the tow vehicle for whatever reason...

You know, actually as an old Arkansas steel trailer with a 6 pin, there's a fair chance that on the small 6 pin, that the center was the brake from the factory. Some did it that way in the early days.

if it is a 6 pin there is more than likely no back up lights, there is left signal, right signal, running lights, and ground. These all have defined pin placment on a pin, the other two positions are S and T, neither of which has a defined purpose, so you find some trailers have the brakes on s, the others have the brakes on T. Normally the other position is used as a charge wire for the trailer.
If you run into a trailer that is wired differently, when you plug it in the brakes lock up. or blow the fuse on the charge wire and you have no brakes.
Thank goodness the manufacturers finally decided to standardize the 7 way plug so that is not really an issue, btw it also gives you one more pin so you can have reverse lights.

your right, they are not backup lights. They are outside loading lights and are connected to the inside spotlight loading lights. We were told that they operate off a converter that should be in the sleeper weekender compartment that should be located close to the fuse box, that powers the microwave, ref. And a/c. There is only these two circuits . There is no converter box. Reckon I'll just do without these lights, but would be nice to have. Should there be a converter box in this horse trailer? I appreciate the help.

Do you have a cord attached to the trailer that plugs into a receptacle? If not, there is no converter. If yes, then the converter should be attached to the end of the cord that is in the trailer.

Ok, converter Busness too complicated for me, so, can a bigger fuse box be installed with more circuits. I would like the load lights, inside spot lights, with a on and off switch, and a cowboy shower on this circuit as well as a 110 plug in on the 4th circuit. Can't all the necessary wiring be ran in pvc pipe under the trailer to the fuse box. Seams to me it would just be like wiring a house. Power comes into the trailer via a 110 male plug inside a receptical box on the right back corner running board of the trailer. We use a heavy duty 110 female cord to supply power. We just need more power for the things we want to have. Those loading lights and inside spot lights pull a lot of amps.

This thread started about back-up lights. Power for a lot of other things is a different matter. Lights, pumps and things like that are generally run off a battery (12v DC) in conjunction with a converter when 120vac is available. The battery operated devices allow operation when no 120vac is available. http://www.progressivedyn.com/rv_products.html has examples of load centers that will operate 12vdc or 120vac with the proper connections. You should probably look at a trailer that has been properly prepared for 12vdc as well as 120vac to get a better idea how all operates. See http://blog.rvshare.com/rv-electrical/ for a basic intro. Many sites on web for all aspects of RV wiring.
