I used a direct wire powercord from the manufacturer of my dashcam bought from Amazon. The Invisicord looks to be about the same thing, but I didn't see output ratings, which you'll have to make sure line up with what your dashcam requires.
In the past week I got the OEM hitch installed (looking back, wish I wouldn't have since it cuts the bumper and is only the Class II hitch), got the legal tint on front windows, and put in the side window deflectors.
I went with the Fortin Evo-One version myself. No aftermarket key-fob so it doesn't increase range, but programmable to set options as well. About a 30 minute install and programming total using the easy to install harness.
