For Computerized Engines?

I don't think that will work in your situation. You have. 'Drive by wire' those are for cable operated TB's. And FWIW I have a rostra cruise and hate it! It fluctuates alot. I also have the factory set up like MARKDTN has and its awesom! But that does you no good. You need a cruise control for DBW which I don't know if there are any aftermarket companies making it. I assume you have the GMPP computer? Do you also have a transmission controller? I was thinking the GMPP computer wouldn't run a transmission. I also don't think it will support any kind of factory cruise control as I don't believe the tables are in the tune. If you are set on having cruise it may be easier to use an older factory PCM, but I honestly don't know which one to tell you to use that would work with the GMPP harness. A converted factory harness would probably work, but if you've already bought what you have I would probably just keep it.

Are you really going to drive the truck long enough distances that you will really need it? I know I use mine all the time, but just throwing it out there.

I bought the controller for the engine and the 4L85E transmission. I actually use cruise control all the time in my Suburban even on a 35MPH road. I one of those guys that just loves CC..now the wife, she won't even use it on the highway which drives me crazy. Thanks for all the help.
