From and 05 F350 to a 16

look to the right of the steering wheel just above your knee near the 4wd switch. It works great. Love my 2016 F350

Super Duty Lariat. I don't remember seeing an exhaust brake on mine.

I had an 03 Duramax and when I went to my '11 F350 the difference was incredible. I think the 03 Duramax was probably comparable to your 05 F350. The difference between my '11 F350 and '16 F350 was not that big ..... much better exhaust brake was about the only thing. What trim level is your new truck?
