Recommended Replacement 7-Way Connector  


I have a GMC 3500 HD dually diesel. It came presided with a 7-way connector in the bed. The left turn signal is not working which I traced down to the connection. Is it possible to just replace the 7 way connector or do I have to do a total rewrite?


Expert Reply:

Yes, you can just replace the 7-way connector. You won't need to completely rewire the harness. You will want to use the Pollak Replacement 7-Pole Connector item # PK11893. This is a direct OEM replacement part and it will plug directly into the socket in the bed of your truck.

I have linked an installation video below.
