Pretty easy to do. I found a YouTube video that steps you through the process. All you need is some wire and a hot glue gun (originally did this for my boat). Eric’s team did the hard work. The whole package works fantastic with a WiFi hotspot. I use the Spark.
The Alpine setup is awesome. Very impressed with the video quality and having the HDMI switch in there future proofs the truck. Awaiting the Grom VL2 update for the 2020.
