Just bought a 08 Yukon Hybrid and I want to pull the ECU so I can get it programmed to disable the AFM. I think I see it by the battery under a smaller fuse block. Is there an easy way to remove it? I have checked the internet and haven't found a definitive answer whether to remove the small fuse box or how to take it out. I usually would take my time and figure it out but it is freezing outside. Any help would be appreciated.
