Chev stubs out wiring under the dash to install a conroller. Only problem the power that should be on the black/red wire is not present. I can see a black red wire hooked to the fuse box in the engine compartment and it does have 12v at that point. I am assuming I need to put a fuse somewhere in the fuse box. Anybody run into this situation? I am trying to avoid doing a continutiy check into that fuse box.
