NGC or GPEC2?

I can't answer that without knowing exactly the year, make, model, engine size your referring to

Ah, gotcha. I guess I was looking more for a general idea if anyone knew. Since I don't have anything at all right now it is hard to give specifics.

If I were to go with an NGC controller, it would probably out of a 2010 Ram or similar. Those come with the SRV control and seem to be the default application when others do this.

Don't feel like you need to go do a bunch of research for me. I am capable, just asked to see if anyone had any personal knowledge.
