I am having blinker light problems after replacing the 7 pin cable on my 2007 T-16 T@B.  The running and brake lights both work but the right turn signal makes the hazards blink and when I hit the left turn signal nothing happens.   I installed this cable https://www.amazon.com/Bargman-54006010-Molded-Trailer-Connector/dp/B00A5VVKUI   and have checked/fixed all the ground and positive wires to the wiring box.   Any ideas?

. . . . running and brake lights both work

. . . . the right turn signal makes the hazards blink

. . . . the left turn signal nothing happens.

Additional Information would be helpful:
  + Did lights work correctly before changing the 7-pin cable
  + Why did you change the 7-pin cable
  +  'Flasher On' do you mean both trailer tail lights flash as if TV flasher was on
      however the TV tail lights themselves do not flash as if flasher was on

Present Light Pattern suggests:
  A  TV left-turn circuit to trailer is open
  B   Trailer right-turn circuit is shorted to Trailer left-turn

Possible next steps
  1 Confirm both 7-pin cable plug and TV 7-pin connector socket are clean and dry
  2 Revisit your 7-pin cable connections at the junction box;
      focus on cable Red and Brown connections
