So alittle history. I have a 2003 yukon xl 1500 denali. I bought the whole harness from a junk hard and the electric fans from a junk yard. I had my Forman program my truck to a 2005 on a tech to to test the wiring and harness and it all worked.

So my question is my buddy had a f350 with a edge cts3 monitor in it. He got rid of the truck but kept the monitor. He let me borrow it for the week before he puts it in his new truck. It works great on my truck. But I noticed it has a turning section. Does anyone have this monitor that can tell me if get a tune to turn my Efans on and load it with the monitor will it stay when I give the monitor back. Or would I have to keep the monitor in my truck for the tune to work?
