Hello, I have an MM3 tuner for sale with all the required cables for installation.
The unlock cable is not pictured but is included.
I bought this setup last year from Double R Diesel.
It was installed in my 2017 RAM 3500 but I believe you can use it in any 07.5-19 RAM diesel and just have Ray write you a new tune on an SD card for whatever you want.
It is in excellent condition and was only in my truck for a year and less than 5000 miles.
Only selling because I sold my truck.
$800 with free shipping anywhere in the USA
Paypal or Venmo preferred.
