I just purchased a used travel trailer. 7 pin connector on trailer and my F150. When connected only the tail/running lights and trailer brakes work. No brake or turn signal lights on the trailer and it blows the mini cartridge fuse on my truck for those functions. I know it has been rewired with the trailer 7 pin being replace. I have checked for loose wires/shorts and haven't found any. The yellow wire from my truck is supposed to be for left turn signal/brake lights. The yellow wire from my 7 way trailer is not connected to anything. But the yellow wire on rv standards is back up lights. I didn't know there are 2 standards for 7way connections. Is it possible for my truck (SAE standard plug) wired to my trailer (RV standard) be the problem? Did someone wire it using the wrong standard? I'm confused, any suggestions?

I have an older motorhome. I want to use the 7 pin to tow a car dolly with an electric brake. When I checked the 7 pin on the vehicle (Curtis tester) all worked but when the brake was applied the 2 turn signal lights on the tester were on and the brake was not. Any ideas?? Help!

I have a set of LED tail lights that I want to put on my old old... OLD caravan. Had a quick attempt before I left on holiday, but everything I tried was a bit of a disaster. Lights flashed and there was actually sound as well. We have had problem for a while each time I connect caravan with the tailgate brakelight flashing. After we hold the brake pedal, this stopped and I always assumed it was holding current somewhere because of Redarc brake controller. But this problem is keeping me baffled. Have always done my own wiring, often running heavier wire than required. Done this for many years and want to change all the lights on the old girl once I get my head around what is happening. See there are units that add resistance to a light but how do you know which one to add. My friend has unit on his drawbar that has the standard wires enter an aftermarket box. We were going to see what is in box because it did same thing. The box is actually sealed shut with gland nuts on each end. I am sure I could do a similar unit if I knew what they have done. Any ideas would be appreciated.

I am wire from go on a 2013 trailer, enclosed 16’. From reading your comment to another regarding relays, My assumption would be 1 relay each, left turn, right turn, running lights, reverse lights, and a general one for any switched LEDS; OR JUST THE FIRST FOUR:?

I have a utility trailer with a 4 way and I use a 7 way adapter to plug in my car. I built an enclosed box on the trailer and I want to be able to run a 120 outlet inside for a small freezer and a couple of lights. How do I go about doing this?
