When I got my truck, it had 200 or so feet (no kidding) of extra wire cleverly routed under the hood, dash, carpet & bed. I can only assume that this was part of the incredibly rare "future CD player/amp/big speaker/radar detector/trailer brake light/wal-mart tach" wiring option, with special dealer installed light up toggle switches.
It also served as a driver entertainment system, since sometimes the bare wires made pretty sparks. I can tell that it's all stock by the way that most of it was put together with duct tape and wire nuts.
It was never put on the option sticker since it was so rare that Chevy would have lost money on tooling up for the printing for only a few trucks.
My truck also came with 3 bridgestone tires and one goodyear. I think that this was part of the nascar option that allowed for better cornering when turning left.
