Got a couple questions about my new truck...

[devgru2011]

1) Simple...Can I later add the upfitter switches?

2) Has anyone read or heard what the best thing I can do for my new 6.7 without voiding the warranty, whether its additives, etc.?

I added the Upfitter Switchers to my 06 after I got it, so I am sure you can. It wasn't that hard.

Adding upfitter switches is the first thing I did to my 2011 SD. I got the switch off Ebay. I wasn't too bad to do but the satalite radio receiver and power mirror relay were kind of in the way for mounting the relay box. I've hooked one switch up to driving lights and one for LED back/up, work lights on the back bumper.
