Is there a way to wire around this?
This is a pain in the butt. Every time I try to turn left, and use the left turn signal the electric brakes engage. Can someone help me out here. Thanks, Tony

 

that probably means your brakes don't turn on with the brake light's.

swap the left blinker wire with the brake light wire and you should be good.

Thanks Man for the help.
That is one of the conundrums of this wiring project. The brakes are working when I step on the brake, but they are also coming on also with the left turn signal! Thanks again, Tony

Disconnect trailer and check the truck connector for proper operation with a DVM. If the truck checks out, then check the trailer wiring for appropriate continuity / discontinuity, i.e. should not see continuity between turn signal and electric brake wires. If there is continuity, then start unwrapping / disconnecting various trailer connectors until the short is found.

If the trailer checks out, you may have a bad ground in the trailer wiring. Ground should be connected through the harness, not the ball hitch. But, if ground was the problem, it would not be left-turn specific, but occur anytime you are powering the trailer lights.

 

He dosen't have a bad ground. If so, nothing would be working. He has his brakes wired to his turn signal. The brakes work when pressed because the brake light is the same as the blinker light. Simply rewire correctly and problem will be solved.

 

It's also possible that you have a couple of bare wires that are touching each other. I had this problem with a cattle trailer once. Things would work fine till we were loaded up and the cattle watered things done a bit. When the moisture got in there, it let the juice from the right blinker feed into the brake circuit.

 

This can also be caused if the 7-pin connector (truck or trailer side) is loaded with water and gunk - it will short between pins. The fix is to clean them out and pack them with dielectric grease.

Yep, you hit the nail on the head. There were only two wires that were wired correctly! The others were wrong. I found this out when I took it to the rv dealer this after noon. They fixed it for me, and all seems to be well.

Now something that might bring about a good discussion. The above link showing how to wire a 7 way is just backwards of the way mine is wired "NOW" The trailer end is the truck end, and truck end is the trailer end. The reason I know this is they gave me the wiring diagrahm in case I ever need to wire a new plug. Anyways does anybody know what is up with two different wiring diagrahms?
They did tell me that trailer depending on what they are used for they can be wired different. Thanks, for the help, later, Tony

 

Once i shoved my 5 pin into the 7 pin adapter upside down.
As i took off and put on the turn signal on the brakes came of full blast, just about put me through the windshield. i though What the.... i thought my trailer was messed up until i found the conector upside down.

 

haha sounds like something we'd wire up here at the house!

 

You really should re-wire it to the proper, standard pattern, with the proper wire colors. It may not matter now, since you have one trailer that will always be pulled by the same truck, but as soon as you need to pull this trailer with another truck, or use the truck to pull something diffrent, your going to have a mess. And if you ever need to work on it or have it worked on again, you better have your handy diagram available. There's alot to be said about standards, especially down the road.

 

I had the same thing only mine was with the tail lights.Turned out to be a bare wire at the brakeaway box.
