Yes, I've seen some extra stuff out by the turn signals, but these are the wires coming out of the trunk wall by the brake booster. I have no idea what sort of bits were in the "frunk" !!! But I'm guessing that since the wiring that I've identified is there, that likely the other 3-4 wires would have been for some reason originally in our cars.....? Likely removed decades and a few owners ago!
