Robb, I owe you a beer. I ordered the behind the switch version this morning. It was on sale for $10 off and both of the last 2 discount codes (FBFORD and FBGM) were valid and saved me an additional 15%. Thanks

I think I like the option of being able to turn it on and off at will. I have started a list of Forscan items I might want to change.

But it also turns off the Battery Management. Its no different than pulling the plug on the battery. If BMS is not running, Start/Stop is not running.

Turning off the BMS is not an issue. I have both disabled on multiple trucks.

There is a 2 wire pig tail that is connected to the negative post on your battery. Disconnect it. It will disable the auto stop/start. It is so much easier than what everyone else is saying to do. Takes 5 seconds.

Any weird messages or lights on your dash afterwards because that would be very annoying.

You're not going to notice anything. It's how the charging system maintains the battery and to some degree affecting MPG by controlling the alternator output. It may be as simple as how long the battery last. You're just defeating the computer taking control of the charging system. Should be fine.
