Either it was ordered that way (look at the options list on glove box door) or someone switched the cluster. |

Re: gauge cluster 3 hole vs. 7 hole
Guages was optional. The only truck that had the guages stock was the Cheyenne super.
I had a 70 CST with the dummy lights and that made a lot of ppl question the originality. |

Gauges were the option, either ordered (by the buyer) or the dealer ordered it that way. Either way the guages are the option, the 3 hole is factory installed (base option) |

You'll need to replace or rewire the harness for this.
