That is not a common car and for us. To make a video we have to have one brought in by a customer. This hasn't happened which is why we don't have a video. We're based out of the middle of Missouri and there aren't many Alfa Romeos around here.

I have linked the installation instructions below so you can see the steps. They are detailed and include pictures and should be helpful getting the Tekonsha item # 118777 harness set up.

The T-One Vehicle Wiring Harness item # 118777 is confirmed to fit your 2019 Alfa Romeo Stelvio. It plugs into existing wiring in the trunk by where your jack is stored. This will provide you with a 4-way vehicle connector that will operate your trailer or accessories lighting functions.
