Well I just installed the harness and the steering wheel with the control for the DIC. Took me and my friend about 4 hours (We didn't know what to do). 1 thing is for sure tho is that you better know what kind of air bag you have in your vehicle if its single or dual! I had to buy 2 harnesses for I messed up the first time. I picked this color for I'm going to be getting the Escalade leather seats
