Difference Between Tekonsha and Curt Trailer Wiring Harness for a 2007 Audi Q7

Question:

Id like to know the difference between this one and 2007 Audi Q7 ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit. Looking at output itself, these two products look same. What makes ZCI much more expensive compared with this one?

What makes the ZCI trailer wiring harness part # 119250KIT worth more the additional cost is that with the harness you don't have to splice into the taillight wiring of the vehicle. Instead it uses sensors that clamp around the wiring and senses when there is voltage instead of having to pierce the wire to sense when there is voltage on the circuit like the Curt part # C59236.
