What Wiring Harness Do I Need for My 1995 C1500 to Tow?
Question:
I have a 1995 C1500 with the tow package. The round trailer connector on the truck was gone. Rusted away. I put a 4 blade flat one on for our pop up camper. How do I tell if I need a 6 blade or 7 blade round connector for the truck? Looking into a different camper.

Expert Reply:
In order to determine if you need a 6-way or a 7-way on your 1995 Chevy C1500, it depends on what functions you need on your trailer. With a 6-way, you will receive full brake light functions as well as turn signals and brake controller output. The only additional capability you will receive from a 7-way is the option for reverse lights on your trailer (if you have them). With that being said, I recommend a 7-way connector because you can always opt out of the backup light function and still have that option available for future use. Also, the 7-way is the most common connector type for your application. I went ahead and attached side-by-side of the different pin functions of the 6-way and 7-way.
Since you already have a 4-way connection installed, I recommend the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat # ETBC7. With this kit, your truck will receive all of the functions previously outlined for a 7-way harness.
