Our member Carlculver wrote me via private message but I wanted you all to see it so moved it here.
1. You mention a j box in your 12v diagram post. Where does that go? Inside or outside on the tongue. Do you have a pic of it in its final resting place?
2. You have mentioned a couple of times about wiring the towing with a 7 way wiring. MY tow vehicle is wired with a 4 way flat. Would you recommend me just get an adapter and wire with the 7 way wiring or is there more to it?
3. If I want to have outlets in my trailer that can charge a phone, I would need a dedicated 12 v outlet right? I bought a 110 v outlet from Costco that has usb plugs in it, but that will only run on a 110 v circuit correct?
4. Do I have to use Romex for all my 110 circuits or can I use 12g stranded?
5. Do you see a problem with me storing my electrical components under the driver side kitchen seat with the water tank? Or should I keep them separate?

Thanks for asking Carl. 1. The J box normally goes under the trailer near the tongue. I often attach an extra piece of plywood to mount the box so that it is securely fastened. The J box can also go inside one dinette (where your other wiring is) but it's better outside since the tow wiring is located underneath. <a data-flickr-embed="true" href="https://www.flickr.com/photos/53634851@N03/51374947778/in/dateposted-public/" title="Tow J Box"><img src="https://live.staticflickr.com/65535/51374947778_ea70dd5abc_w.jpg" width="400" height="300" alt="Tow J Box"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script> <a data-flickr-embed="true" href="https://www.flickr.com/photos/53634851@N03/51375451419/in/dateposted-public/" title="Belle Tow Wiring (4)"><img src="https://live.staticflickr.com/65535/51375451419_83271a3f8c_w.jpg" width="400" height="300" alt="Belle Tow Wiring (4)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script> 2. There is no adapter to go from 7 way trailer to 4 way vehicle connectors. You can make one but I don't recommend it. The 4 way has no brake control ability and it does not charge your battery on the road. The 7 way does both and also has an spare space as well. (sometimes used for trailer back up lights) 3. If you install a 12 volt system, the cigar plug is the way to go on charging your phone and other devices. The USB in your 110 outlet will not charge if you are not on shore power. Another option is a portable jump starter battery power station. It has USB outlets, a light and sometimes an air compressor. <a data-flickr-embed="true" href="https://www.flickr.com/photos/53634851@N03/35250424810/in/album-72157683590489800/" title="7 way Tester (6)"><img src="https://live.staticflickr.com/4253/35250424810_9e5e95ecbb_w.jpg" width="400" height="300" alt="7 way Tester (6)"></a><script async src="//embedr.flickr.com/assets/client-code.js" charset="utf-8"></script> 4. Yes, use Romex to wire all 110 circuits. Stranded automotive primary wire is used for your 12 volt system. 14ga works well inside the trailer. 5. I see no problem with electrical in the same space the water tank is in. Be sure that the electrical has space for you to work on it if need be. |

Vikx,
Regarding this one:
2. There is no adapter to go from 7 way trailer to 4 way vehicle connectors. You can make one but I don't recommend it. The 4 way has no brake control ability and it does not charge your battery on the road. The 7 way does both and also has an spare space as well. (sometimes used for trailer back up lights)
So I should just stick with my 4 way flat and not utilize my brakes?
Would something like this be doable or would you recommend I stay away from this type of alteration?

I think you should install a 7 way receptacle on your vehicle. You've already got the ground and RT, LT and TM (tails and markers) in the 4 way flat. Having the 4 way connector as well is handy. I hard wire my 7 ways rather than use the 4 way flat connector to your existing 4 way. (they tend to corrode and lose contact) Snip the 4 way connector off and crimp connect the wires. NOTE: be careful not to mix up the 4 way and 7 way color codes. Read here: vintagetrailertalk.freeforums.net/thread/11345/when-tow-lights-screwyI do NOT recommend the hack the video is showing. Do not cut the extra wires. If your trailer has brakes, you should connect them. You will need the power wire to charge a battery if you have a 12 volt system. The wires can be taped if you don't want to use them right away but eventually you will need them. Mount the bracket on your vehicle and it will make it easy to hook up a 7 way trailer or 4 way flat. Hope this helps. |
