Yes to all three questions. The first photo is taken prior to me removing it from my truck after running it about 3 weeks. Everything does work on it with just the big plug. Not sure what the little one does....have you mounted this on your truck before? Will you ship to California? do all the gauges work properly even though you are only using the big plug?
It is only stored in the cluster, but if you go somewhere that "officially" records your mileage (in their system), then you are stuck with it. That is why I got one of these with mileage very close to my truck.Is the mileage stored in just the cluster and not in the trucks ECU? In other words, if I install it and get a smog check later, is there gonna be a discrepancy between what the smog machine reads and what the tech sees on the dash?
