Wiring Problem

Have constant power at the left turn/stop terminal on my 7 pin connector. checked and cleaned all the connections behind the bumper, but still have the constant drain.

There is no constant power on the trucks left turn signal, only at the trailer harness.

Any ideas on where to start checking?

Thanks
Stephen

what is the problem ? directionals inop ? trailer wiring ? etc.

In the instrument panel fuse box there should be a fuse for left trailer turn/stop. Check for power on that fuse. If there is and the brake and turn signal are off than I would suspect the turn signal/flasher module. They are fairly common to go bad
