Trailer turn signal and my strobes. Someone save me!

Let me start off by saying ive looked all on this forum/website and cant find anyone who's has a similar issue.

On my flip axle, all of my lights work however, when I turn my passenger side turn signal on, my driver side one comes on also!!! I know its somewhere in the trailer because its doing the same thing on the trailer tail lights also. (rgn w/ flip axle). I absolutely dont like going to a truck stop shop. But, here I am at the TA in Spartanburg SC,.....

someone save me!!!!! And if not, at least this thread will be here to help someone who has future issues.

 

Thanks. But, unless I passed over it, I didnt read anyone having a similar issue.

 

Yeah truck works fine with or without being hooked up to my trailer.

 

I unhooked my pigtail in the rear that goes from my trailer to the flip axle and same thing, so I know its in the trailer.

 

Yeah we were typing about the same time...I unplugged pigtail from trailer to flip and still doing it

So, should there be a box on flip and trailer?
