LIke many, I don't like the default setting for the start stop system...and I ordered the wiring harness to install in my 2020 Forester. However, the item I received from Amazon did not come with instructions. So, I google the install instructions and while the seem pretty straightforward, the work is being done in and around the cameras. Has anyone done their own installation and if so, is it indeed pretty straightforward? Are any special precautions required? Or...if there are pitfalls, should I have my dealer do the install? If so, what are the usual costs for labor? I will be SO glad to get rid of the default stop start setting!
