Question:
I just purchased the Draw Tite class III hitch #75528 for my 2017 Chevy Traverse paired with the T-One 7 way wiring harness #118271. Both the T-One brand 7 way #118271 and the 4 pole #118271 harnesses come with two relays. However, the Curt T-Connector harness #C56245 comes with three relays. Why does the Curt harness come with a third relay? Is a third relay needed for the T-One 7 way harness #118271 I purchased? Thanks in advance!

I have taken a look at both instruction manuals, the T-One Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector, part # 118271, and the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector, part # C56245. Each of these wiring harnesses use only two relays during their installation. The Curt wiring harness includes an extra relay and both harnesses include an extra 30A fuse.
I have included installation videos of both wiring harnesses below.

I have a 2017 Chevy Traverse LT, and purchased the wiring harness from your company. I need the t-connector for that harness and my vehicle. the order number from etrailer is 121358649, and the part number is C56245. My vehicle has the wiring on the driver's side underneath the vehicle. It is in two parts, and can be separated to insert the t-connector, then I can plug the wiring harness into the side of it.
