Thanks for the response. I may have not explained the problem correctly. At the rear of the truck I have good lights, break lights and ,left and right turn signals. However when connect a trailer to trailer to the factory installed trailer Pig tale, I never get turn signals,all out lights work, just no turn signals, Any thoughts/ Wayne

Could be I did not read it right... it was after a long day
If you do not have stop / turn circuit active, 1st thing I would check are the fuses for the trailer tow adapter stop / turn signals.
These are in the BJB ( aka battery junction box, engine compartment fuse panel ) fuses #19 & #20.
Strange that both are blown, but not unheard of.
When you replace the fuses, check with a meter at the 4 pin / 7 pin adapter before plugging in the trailer. use the ground on the trailer tow adapter just for good measure ( to make sure you are getting ground from the trailer tow adapter ).

I'm still trying to decipher the symptoms.
Are you saying you have trailer running and brake lamps but no trailer turn signals while the lights ALL work properly on the truck itself? If so, that is an illogical combination that should not be possible with factory wiring. if the fuses that sscully specified are blown, you wouldn't have trailer brake lights.
PS. The brake lights and turn signals are the same two wires. There is no single brake light wire on the factory trailer wiring adapter.

Unless you have some weird kind of 5-wire conversion.....
Okay, please pay attention to this.
The turn signals and the brake lamps on the trailer are the SAME THING. The only thing that is different is they're both turned on at the same time for brake lamps but one at a time for turn signals. These bulbs operate in parallel with the truck's lamps with the minor exception that they are individually fused (so a trailer fault won't take out the truck's signals).
