Wow dude. You're awesome. Love guys like you that have so much knowledge to lend.
Well I really want to add this to my truck as well.
It should be doable as it's been done before with F150s and the setup is almost identical. I don't think adding the hardware will be a problem. More likely, it will be getting FORScan to work making changes in the code in whatever modules need modifying to get it active and working.
For example, there's a fantastic thread where a fellow is adding a heated steering wheel (something else I want to do that's even more complicated than adding BLIS). The challenge for that project was the fact FORScan wasn't programmed to even look for the Heated Steering Wheel module because it was never available as an option. But, low and behold, he managed to talk the FORScan developers into adding that capability to the program. So, now it can be done!
well the blis module for the side is in the rear quarter panel area, and ARE not attached the skin, they are attached to the frame structure,
mirrors only have the icon flashy light thing
Yeah we need to see some pics of how and where the SOD modules are installed. I found pics of 2015 and 2016 modules that show a big difference between left and right (likely for the brackets and not the modules themselves). Tasca shows only one part for 2017 and that resembles the left module for 2015/16. Also, the 2017 part # is ridiculously expensive (almost $1000 list) while other part #s for similar modules on other vehicles are less than $200 each.
