4-Way Trailer Connector Recommendation for a 2004 GMC Sierra

Question:

Im looking for a wiring harness for a 2004 GMC Sierra extended cab pickup that did not come with a factory tow package. For my wifes jeep, I purchased a T connector that plugged into the tail lights and ended with a 4 flat connector. Is there a product similar to that for this truck? Thanks,

Your 2004 GMC Sierra should have come with a round 7-way at the rear of vehicle mounted in the bumper by the license plate. If you have this and are looking for a 4-way as well you can get the part # C56584. This will install in line with your 7-way and will give you a 4-way you can use.

Or if you are missing the 7-way you could use the # 74682 as a replacement. This also comes with a 4-way connector mounted to the side of the 7-way.
