For a replacement 7-way for your 2006 Chevy Trailblazer you would want the Tow Ready 7-way part # 74682. This also has a 4-way built into the side of it. You would just need to remove the harness from the back of your current 7-way and then plug it into the round connector of this harness.

For a replacement 7-way for your trailer you would want the part # H20043. Since trailer wiring colors can vary from vehicle to vehicle your best option would be to use a jumper cable from a car battery to apply voltage to all of the wires to determine what circuit they carry and then wire them to the 7-way accordingly.
