So I was messing around trying to hook up hook up our alarm system so I was trying to find all the wires before I started cutting anything and I decided to put it back together because my wife needed the truck for work and I didn’t wanna know in the boat. I’m in now so now it will start, but it don’t have any interior lights no light no windows the dashboard will light up, but nothing works on it. The only reason why I think it is because I took the factory security system out of the computer and I don’t really see what I could’ve done think anybody can give me a diagram and the BCM I think really appreciate it
