Has the speedometer quit? If so then replace the sensor on the rear differential.

The p2509 is usualy a bad Battery

Found the loose connection. my issue is no left signal and brake light , but running light is on all this is on the trailer plug. The fusses are all good I traced it to between fuss controll and fire wall. Could it be the( TIPM)?

You don't have a tipm.

If I don't have a TIPM where can I find where the wiring splits from truck to trailer wireing

 

[jhenderson]

Separate trailer fuses in the fuse box under the hood. Trailer wiring is all separate from truck wiring.

 

[tinaanddale]

Fusses are all good there has to be a mod where the wireing splits

I have been searching where does the wiring split and go to the wiring harness for towing I was told I don't have a tipm I know there is something where the connections split ,I need to find out before I go poking wires I know there are fuses for towing and they are good . the reason I am searching is the left turn and brake light does not work but the right side is all good. i would like to find the issuer because I am fixing to get on the hwy with my camper and cross state lines

If it was a mechanic that said you have a TIPM then go someplace else - you don't have one.
The FCM on the drivers side and under your fuse box controls wiring to trailer.

You don't have a TIPM but the PDC and FCM are essentially the same thing. The good news is if the FCM is bad you can replace it seperately, if they haven't combined them from a dealer.

The PDC distributes the power and handles the fusing. The FCM contains relays that activate the circuits. The relays go bad and the circuit does not work. With the TIPM's the dealer can reset them once or twice but not sure about the FCM. The only time I know of the relays went bad they had to be replaced. If you dig around and want to attempt it they can be removed and soldered back to the FCM control board.
