The cause of both turn signal lights flashing together would almost certainly be attributed to a poor ground. There are several grounds you will want to check which include one for each light, the trailer side trailer connector and the vehicle side trailer connector. One of these locations will more than likely contain the problem you are experiencing. It is important to make sure each ground is attached to a bare metal surface. It may be necessary to undo the ground wire and then use some 80 grit sandpaper to smooth the surface. Once the surface is free of paint or dirt you can then reattach the ground wire using both part # 101131802 and part # DW05705-1.

Once you have checked and secured the ground let me know if the problem is fixed or if you need further troubleshooting advice.
